CAT COMMUNICATION - BODY LANGUAGE
Cats which communicate mostly with other cats use mainly on body language and scent - this is their "native language". Their body language is subtle, but many owners and cat workers learn to read the more obvious cues.
A BRIEF SUMMARY OF FELINE VOCALISATIONS
There are at least nineteen different types of "miaow" which differ in pitch, rhythm, volume, tone, pronunciation and the situations in which they are used. The familiar purr may be used for contentment, self-reassurance or an invitation for close contact. Injured or sick cats (and even dying cats) may purr because the sound frequency has been shown to soothe the cat and to promote healing. The "miaow" and purr are just two of at least thirteen different categories of sound made by cats: caterwaul, chatter, chirrup (chirp), cough-bark (rare in pet cats), growl, hiss (with or without spit). meow, mew (of kittens), purr, scream, squawk, yowl and idiosyncratic sounds (i.e. sounds peculiar to an individual cat). There are probably over 30 different sounds. The number of sounds a cat makes depends on how much the cat communicates with (a) other cats and (b) other non-cats e.g. humans. Cats which communicate with humans a lot have a wider spoken vocabulary because they learn that humans understand sounds but cannot easily understand feline body language. Cats learn which sounds elicit the desired response from their human companions and some cats have a wider "vocabulary" than others. Purring and vocal communication is discussed in detail in "Cat Chat - Can Cats Talk". You may also wish to read "Do Cats have Emotions"
HOUSECATS, FERAL CATS AND BIG CATS.
Housecats develop a wide variety of sounds to alert humans to their needs and intentions. Many are variations on mother/kitten meow or chirp sounds which the cat has adapted in order to "speak" to non-cats. This is quite logical since the cosseted housecat remains dependent on humans i.e. a permanent kitten. Others are adult sounds such as the caterwaul (used in a sexual or territorial context) or the cough-bark (a fear/anger sound usually accompanied by a front paw stamp).
Cats kept with other cats are communicating with each other all the time through body language and scent. They are communicating with their owners all the time too, it's our problem that we can't understand their language. Cats work out which sounds elicit suitable responses from humans (positive feedback) and learn to make those sounds in order to achieve a particular aim e.g. for a door to be opened. Since humans are in charge, it makes sense for the cat to learn to communicate vocally though it must sometimes be frustrating to a cat which has clearly communicated its mood using facial expression to have to explain things vocally to humans. It is the feline equivalent of speaking slowly and loudly to a foreigner!
Cats have different personalities and this affects how much they want to "speak" to humans. Personalities are partly controlled by genetics and partly by upbringing so both factors contribute to how much an individual cat talks. Like some humans, some cats probably have nothing much they want to say! Also, some owners are good at reading cat body language and the cat simply doesn't need to vocalise quite so much.
Most cats tend not to vocalise with strangers unless the stranger approaches them (less often the cat approaches a stranger for food or fuss). The vocalisation then depends on whether the cat is fearful or friendly. If fearful the cat may hiss or growl and thrash its tail (agitation) to warn the stranger not to approach any closer. If friendly it will meow or purr and its tail will stick upwards (greeting) inviting attention, or possibly begging for food. Stray cats living around restaurants learn to beg appealingly to diners - this is linked to food begging, though some do enjoy interaction and a fuss.
Cats also learn to communicate with other household animals e.g. dogs. They are less likely to vocalise because dogs can interpret scent signals and can learn some feline body language. Sometimes the cat must reinforce its unspoken message with a hiss if the other animals ignores or fails to understand body language. Like cats, dogs also rely greatly on body language. In a household setting, cats and dogs are in close enough proximity for long enough that they can learn each other's body language to some degree.
Feral cats rely more on their native body language. They don't need so many variations of "meow". They use all the "major sounds" e.g. yowl, growl, etc but they rely much more on non-verbal communication to convey meaning - posture, gesture, facial expression, tail position, whisker position, ear position, scent-marking - with vocalisation often being a last resort to augment or reinforce the non-verbal communication or when they can't see each other properly. Feral cats with little or no contact with humans don't learn so much "spoken" language as do housecats. They have no need to learn a vocalised "second language" because they are communicating with native speakers of "cat body language".
Details of big cat vocalisation is out of scope of this article. Big cats have their own repertoire of sounds e.g. the rumbled greeting of lionesses and the distinctive "chuff" of tigers. Two important differences are that big cats such as lions, tigers, jaguars and leopards cannot purr because their throats are built for roaring. Conversely, the small cats, puma and cheetah, screech or yowl rather than roar (this is discussed in Cat Chat - Can Cats Talk"). Although there are a few reports of purring-type sounds (a breathy groaning sound rather than an in-and-out purr) from lions and tigers, it seems that a cat can either purr or roar, but not both. Purring is also found in the cheetah, puma and most small cats such as the serval and ocelot. Cubs may "mew", but adult big cats do not "meow". Individual big cats are sometimes tamed e.g. if hand-reared, but big cat species have never been domesticated in the same way as the housecat. "Cat Chat - Can Cats Talk" suggests that living alongside humans has meant that the process of evolving a domestic subspecies from a wild ancestor went hand-in-hand with increased vocalisation in domestic cats. Big cats have not been through thousands of years of evolving a domestic subspecies and have not needed to communicate with humans.
THE LANGUAGE OF SMELL
The first language a kitten learns is that of smell. It is blind, deaf and defenceless but it has well-developed senses of smell and touch (including warmth detection) to guide it to the mother cat's nipple. A kitten recognises its own scent on the nipple and aims for the same nipple each feeding time. The mother identifies her kittens by their individual scent and by her own scent on them. This then is the first mode of communication the kitten learns. Scent will play an important role all through the cat's life.
Cats have scent glands on the chin, lips (in the corners), temples and at the base of the tail. Each cat has its own scent signature. When it washes, a cat transfers its scent from these glands to its fur. This scent is then transferred to objects the cat rubs against - a fencepost, twiggy plants, a doorway or a person's legs. For example, most of my doors have a grey greasy mark at cat's cheek level where Cindy marks them over and over again.
They use this scent to mark areas and objects around them, other cats, humans and other animals in the household. This helps create a communal smell. A new cat must literally rub up to superior members of the group to mix their scents before becoming an accepted member of the group. Its home territory also has a smell profile and any new smell - another cat or even a new piece of furniture or a scent carried in your shoes or clothing - can cause insecurity and lead to a frenzy of marking activity! When a cat scratches it leaves both a visual marker and a scent marker from its paw-pads. It will mark its territory by rubbing its chin or cheeks onto upright objects (posts, chair-legs, door edges etc) and also by spraying or depositing faeces. Scent is so important that blind cats can navigate around their indoor territories using a combination of memory and scent trails.
Cats who are familiar and friendly with each other often have a greeting ritual. They use a similar ritual to greet their humans or other household animals. They rub their head, flank and tail against the other cat or person to exchange odours. They hold the tail straight up so that the other cat can sniff the anal glands. When stroked, cats raise their rumps even higher (almost standing on tiptoe) to invite you to sniff their anal glands!
The language of smell manifests itself in a less pleasant - to humans - way as well. Tomcats spray pungent urine to mark their territories and to advertise their sexual status. It's the equivalent of a human marking out boundaries with flags advertising his age, healthiness and his readiness to service fertile females. The urine is sprayed roughly at nose level, making it unmisable to other cats - and unmissable to humans if it is sprayed on doorposts, dustbins or indoors! In areas where territories overlap, tomcats try to spray over other cats' scent markings as well as refreshing their own scent markings. An unfortunate side effect is that some spray indoors in response to scents carried in on shoes or clothing. Female cats also spray and for the same reasons, though less commonly than males. Neutered and unneutered cats of both sexes will spray and Siamese cats (either sex, neutered or entire) are often notorious sprayers.
Faeces is also a scent-laden marker. Although common wisdom is that cats fastidiously bury their wastes, they may use faeces to mark territory - a behaviour known as middening. Middening cats deposit their faeces in a prominent spot (often on top of a tuft of grass or the middle of a path), often choosing the same place again and again to advertise their continued presence. Middens are usually located at disputed areas of territory where challenges are likely to occur. Sometimes this is indoors, the usual place being the bed. A cat which has been upset by an intruder or unusual event middens in the place which smells most strongly of its human family, reinforcing the family bond. Humans don't see it the same way.
When a cat scratches a tree, scratching post, wallpaper or doormat (or even the furniture) this does several things. As well as stropping the claws and exercising the leg muscles, it deposits scent from the paws onto the object. The height of the scratch marks may be important in communicating the cat's size and strength to any potential challenger. The height of scratch markings above the ground appears to be important to tigers in advertising their age, size and strength and the same may be true of domestic cats.
Spraying, middening and scratching ensure that cats are communicating with each other even when not physically present. Though these behaviours may be annoying to owners, to cats these scent laden markers are signposts, boundary markers and personal advertisements.
Unlike dogs, cats do not generally co-operate to hunt or form cohesive packs. Cat colonies are much looser groupings than the strictly hierarchical wolf-pack. They haven't needed to evolve the social rules for pack living. They mix with other cats when mating, raising kittens and in sociable groups such as feral colonies or multi-cat households. Feline body-language is complex and subtle with ate least twenty-five different visual signals used in sixteen combinations. There are doubtless many other, more subtle, nuances which we don't notice. Most owners can learn to recognise at least some of their cats' visual signals.
The most dramatic body language occurs when rival males meet, during courtship or over fiercely protected territory (in general, cats are happy to let other cats pass through their territory or even time-share it, but the core territory may be fiercely protected). Neutered cats generally have less extreme interactions. Many visual signals are displayed when cats play, either on their own, with other cats or with humans.
The aim of body language is to convey a message and to avoid or end physical confrontation. The aggressor or challenger would prefer to win its case without resorting to teeth and claws since it could be badly injured in a fight. Many disputes are resolved by staring each other down and yelling. Sometimes it is so subtle that humans cannot tell there was potential conflict - the dominant cat, having won the confrontation, simply walks away from the loser, sits down and looks in another direction (or start grooming - a favourite feline activity).
Body language has to be read by looking at the whole body - the face, the posture and the tail position. Looking at one of these in isolation is misleading since they all combine into an overall message. For example when a cat arches its back, is it upset or is it friendly? The same basic posture means two very different things depending on the facial expression, whether the fur is bristling and the eyes and the ears.
A cat's head position tells us several things. If its head is stretched forward, the cat is encouraging touch or trying see its owners or another catís facial expressions. This is a greeting message. In conflict, an assertive or confident cat may raise its head, but an aggressive cat will lower its head. An inferior or submissive cat will also lower its head submissively. An inferior cat which is fearful and defensively aggressive will raise its head though. To understand the message, you have to look at the other end of the cat - its tail!
If the cat keeps its head down, pulls in its chin and turns sideways to prevent eye contact it is conveying a lack of interest and the fact that it is not threatening. It will also pull in its chin when relaxed. To understand the whole message you have to look at the way it holds its body.
Friendly cats will head-but or head rub and will extend this into a full body rub. Cats will also head-butt and body-rub their humans. The nose-bump is another friendly greeting. When cats meet, they sniff each other's faces - sniffing the scent glands around the lips to determine the identity of the other cat and whether it is a family member or not.
Sara and Ginny head-butting. This is a friendly action and often ends up as a whole body rub and maybe also tail-twining.
The back-turned ears and the posture (pulling away, but head turned to face the person approaching it) shows that this young cat is flinching away (see later for details on posture). It had just arrived at a shelter and was friendly but nervous of its new surroundings.
Humans love eye contact - it is friendly. For a cat, prolonged eye contact is an assertive, or even threatening, signal. The classic case is when several people are in a room for a social occasion and the host's cat walks in. It unerringly goes towards the person who doesn't like cats. Is it simply being perverse? The answer is in eye contact. Cat lovers will be watching the cat, hoping it goes to greet them. Those who don't particularly like cats will ignore it, hoping it will leave them alone. For the cat, the eye contact made by the cat lovers is somewhat threatening. It avoids them. The people who don't particularly like cats are not making eye contact - to the cat, they are signalling that they pose no threat. They are being polite in cat terms, so it goes to socialise with them.
Rival cats try to out-stare each other to resolve conflicts. When a cat realises it is being watched or stared at, it may stop whatever it is doing, assess the "threat" and then continue with its activity, but in a far more self-conscious way. The cat knows it is being watched and becomes uncomfortable. Only when it is no longer being watched, does it relax again. This is one reason it is hard to study cats! Slowly blinking breaks up an aggressive stare and is a reassuring signal between cats and between owners and cats. Yawning is even more reassuring! When relaxed, most cats have their eyes half-open, giving the appearance of being half-asleep.
Cats have excellent peripheral vision and tend not to stare directly at something unless they are getting a fix on a moving object in preparation for pouncing. When a cat sits day-dreaming, it appears to be not looking at anything in particular. It is actually taking in a great deal of information with its peripheral vision.
Some owners deliberately engage in "blink kissing" with their cats - when looking directly at a cat the owner blinks in a slow and deliberate manner. This uses the cat's own language to say "I am not threatening you, you can relax". The cat often blinks in response and then acts in a self conscious way, perhaps fluffing itself up or grooming. While some owners claim "blink kissing" helps the cat-owner bond, the cat would no doubt prefer the owner to politely gaze into the middle distance and observe the cat using peripheral vision instead of a direct gaze.
Interestingly, behaviourists have tried the "gaze and blink" trick with big cats in zoos and have reported that lions and tigers will blink back at them. A few readers have emailed me having tried the same. This is not recommended since a direct gaze is a challenge and a big cat has no real need to reassure us of its friendly intentions - it sees us as potential prey.
The pupils of the eyes convey part of a cat's message. As well as dilating or contracting according to the amount of light around, they contract or dilate to indicate mood. Dilated pupils accompany fear, aggressive excitement and also the mild excitement of seeing its owner, a feline friend or even dinner! The more fearful a cat is, the wider its pupils expand - it is as if the eyes are trying to take in as much information as possible. An angry, confident cat has narrowed pupils. It may be ready to provoke a fight and by narrowing the pupils it can focus better on detail and also reduce the risk of damage to that part of the eye.
Nutmeg, the cat in the photo is alert and interested (whiskers pricked forwards), but her dilated pupils indicate apprehension. She was, in fact, rather apprehensive of the strange apparatus (the camera) pointed at her at relatively close range. However her pricked whiskers indicate that she is not actually frightened.
The eyes alone cannot convey a whole message and if the cat is blind, its permanently dilated pupils cannot convey a message at all. It is necessary to look at the rest of the cats face to piece together what it is saying. This sounds like a lot of work, but most humans read human expressions instinctively. If you can read human body language and facial expression, a little practice is all that is needed to learn the cat's facial language.
Cats' ears are extremely mobile. With 20-30 muscles controlling them. They can swivel through 180 degrees and move up and down. They can be pricked forward or flattened sideways or backwards. The Scottish Fold cat, with its permanently folded ears, is at a slight disadvantage here. A cat can move its ears independently of each other. Not only do they pan around like radar dishes, scanning for any sound, the ears are important instruments of communication - they act like semaphores signals.
Some wild cats species have dark ears with white or pale markings on the back. The make the ear signals even more visible, especially at dusk and dawn when cats are most active. Ear tufts, such as seen in the lynx and caracal, also emphasise the movement and position of the ears and may help short-tailed species (e.g. lynx) compensate for their lack of tail. Note: in experiments with caracals, the ear tufts also help pick up sound vibrations, caracals whose ear tufts were trimmed off were less able to hunt small prey in long grass.
When content and relaxed, a cat sits with its ears facing forward but tilted slightly back. However, its ears demonstrate that the cat is alert even when it appears half asleep. If the cat's attention is caught by a noise or a movement, its pricks its ears more upright, maybe swivelling one or both to track the source of the noise.
If the cat grows anxious, its ears move slightly back and flatten down. An fearful cat has lowered ears. The more anxious or fearful the cat is, the flatter the ears until they are lying straight backwards, flat to the skull. If the cat is fearful but aggress, the ears flatten sideways - a combination of the forward pointing "alert" ears and the flattened/lowered "fearful" ears.
If one ear is flattened and the other isn't, the signal is more ambivalent and the cat isn't yet sure how to react to what is going on around it. Generally it will withdraw a short way in order to consider the situation. While considering, the ears shift and change as it processes stimuli and possible responses. A similar highly mobile state occurs when the ears are panning round to catch noises, but the cat's entire demeanour will be one of alertness or interest, probably with a slightly twitching tail.
Ear flicking or "ear flagging" (flattening and horizontally moving one ear) has been reported by some of my readers. John Whitehead, a biology teacher in the UK, suggests it is also used as a way of pointing in a certain direction. This, he believes, can be seen when a cat is on a "walk through" of another cat's territory and encounters the resident feline. After a pause and some facing down, the visiting cat is signalled in a direction by the resident cat flicking one ear. He believes that some pet cats extend this to communicate with humans, for example when a door is opened and the cat given a choice of in or out, it may signal its intention to stay indoors by ear flicking towards its favourite chair. I am not convinced about ear flagging, but it merits further study. A more usual explanation is that the cat is in two minds about something and its uncertainty results in ambiguous ear signals.
THE WHISKERS AND MOUTH
The whiskers are not just for judging the width of gaps or the proximity of objects. They are also mobile and help to indicate the cat's mood. In a normal relaxed "neutral" state, they are held slightly to the side. As the cat becomes more interested in something around it, the whiskers perk forwards, ultimately coming forwards in front of the muzzle (a good position for the shorter whiskers to detect the bite point on the prey's neck). The cheek pads also seem to swell out as the muscles pull the whiskers into position. If the cat is fearful, it pulls its whiskers back alongside its cheeks to signal that it is non-threatening. This also makes its face look smaller.
A cat rarely uses its mouth to signal aggression. An open-mouthed yawn may signal non-threat. An open-mouthed snarl or hiss show that the cat feels threatened and defensive. Growls are delivered with the mouth only slightly open. The teeth-bared grimace is not a dog-like snarl, it is the cat's flehmen reaction - one way in which a cat analyses scent signals.
Flower is yawning. Her whiskers are pricked outwards and slightly forwards. Her ears are pricked (the flattened one is actually listening to a sound!) indicating alertness. She is neither aggressive nor defensive and though relaxed, it is still alert to its surroundings.
When reading a cat's expression, be aware of its surroundings. Affy may look angry (narrow pupils, ears back) but she is actually yawning. Many cats partly flatten their ears when they yawn widely.
Flower, the cat in the photo is yawning - its whiskers are pricked slightly forward, its ears are pricked (the flattened one is actually listening to a sound!) indicating alertness. The cat is at ease - neither aggressive nor defensive and though relaxed, it is still alert to its surroundings.
Some cats sit with their tongue sticking out a little. This seems to show relaxation and contentment or that the cat has become interested in something. On the one hand it gives the cat a rather daft look. On the other hand it gives the cat a look of concentration. Licking the lips may indicate anxiety or anticipation depending on what is happening around it. Cats may lick their lips slightly as food is presented, but reserve real lip-licking for the after-dinner wash.
When cats yawn they are not so much bored as signalling reassurance and contentment. Sometimes yawning at a timid cat (and blinking slowly while gazing into space) will help it to relax. Cats also yawn during their waking-up routine e.g. as they stretch. When a cat yawns its whole face appears to split open!
The tail is an organ of balance, a rudder/counterbalance for manoeuvring at high speed and a means of communication. While hunting or stalking, the tail is kept almost horizontally behind the cat. This prevents it from fouling in low-hanging shrubs and prevent the prey from seeing a telltale tail. It may spring upright during the final rush. The tail also conveys a catís interest and concentration with a twitching movement as it corners its prey. You can also see this twitching movement, usually just the tip of the tail, when a cat sees something interesting through a window. When a cat is crouched low to the ground, edging forward towards prey, the slight twitch of its tail indicates how hard it is concentrating.
The tail is an important tool for communicating with other cats and with humans. It is highly mobile: side to side, up and down, graceful and slow, thrashing and whip-like. It can be a sleep coil folded around a sitting or sleeping cat, a fluffy scarf across a curled cat's nose or an erect bristling bottlebrush when the cat is frightened. A mother cat may also use it - deliberately or accidentally - as a toy for her kittens.
Relaxed, alert and confident - ears pricked, whiskers slightly drooping, tail drooping from horizontal. Shampoo is off to greet a friendly person.
These two ferals first greet each other by stretching and then by rubbing and tail-twining to mix scents to reinforce their bond.
When a cat is relaxed, confident and alert, it walks with its tail horizontally behind it or even slightly drooping. This prevents the tail from becoming snagged in undergrowth. If it meets a friendly cat or friendly human, the tail goes up like a flag-pole to convey its friendliness. If it is friendly but cautious of the other cat or person, the upright tail is hooked over at the tip indicating a degree of uncertainty. A mother cat's upright tail is a signal for her kittens to follow and their upright tails may help littermates or their mother to spot their whereabouts.
A spraying cat also adopts the tail up posture, tail a-quiver and treading/dancing with the hind feet, trying to lift its rump higher. When a cat meets its owner and wants to extend a friendly greeting, the tail goes up and quivers, but there is no spray of urine. It is the cat's version of "I am SO happy to see you, I am overcome with emotion." Many owners refer to this as "feather-dancing" because the upright tail resembles a quivering feather. It may pull its upright tail slight forwards over the back, kinked down a little at the tip and give a little chirp at the same time. This invites the cat/person it is greeting to sniff the anal glands and confirm its identity as a group member.
When kittens greet their mother, they run to her with their tails upright like small flag-poles. They droop, twine or rub their tails around their mother's rump or tail to solicit food from her. Adult cats also tail-twine. They entwine tails with friendly cats as they rub against each other (the tail has scent from the anal glands on it from where the cat has washed it). They also wrap their tails around human legs or objects. This both marks the leg or object and, if they are tail-wrapping part of the owner, is an attempt to get attention, fuss and food!
When a cat is at rest, but readying itself for action, it sweeps its tail erratically from side to side. It seems to accompany the feline thought process of "do I or don't I?". As it becomes more alert or more emotionally charged, the tail swishes faster, wider and in a more regular manner. If the cat is lying on its side, the tail will be thumping on the floor, often loudly. Though this is most often associated with anger, it may also indicate another highly charged emotion - some cats thrash their tail in ecstasy when being groomed. Violent thrashing therefore indicates high excitement or imminent aggression. A swishing or thumping tail is sometimes an invitation for another cat to join in a bout of play. Very few cats wag their tails in happiness like dogs.
The other easily recognisable tail signal is the upright bottle-brush tail. This indicates that the cat feels seriously threatened and has become defensively aggressive i.e. it would rather get away, but if provoked it will defend itself. The tail doubles in size and the hair on the cat's spine also stands erect (pilo-erection). As well as indicating the cat's state of mind, it makes the cat look bigger than it really is in an attempt to make the aggressor leave it alone.
The "inverted L" is a sign of conflict. The first inch or so of the tail is horizontal and the remainder points straight downwards. The "Inverted U" or "Horseshoe" tail, often with the fur erect, is defensive aggression, but can also be seen during the "mad half hour" when the cat rushes around as though it has the wind under its tail. Kittens frequently use the inverted horseshoe during play and mock-battle. When the cat stretches its forelegs, its tail may come right forward over the head. When it stretches the back legs, the tail may end up upright and hooked over.
Sometimes the upright tail is jerked suddenly and briefly forwards. This seems to be the feline version of the human "two fingers" obscene gesture. It denotes mild irritation or derision. You might see this if you address your cat as it is walking around - the cat acknowledges you, but has its mind set on other things and is making a "So what!" exclamation.
As previously mentioned, a defensive cat erects its fur to appear bigger than it really is. A dominant cat will also try to look bigger than it really is, perhaps swaggering a little. In both cases, the cats are bluffing to try to avoid conflict.
An aggressive cat will straighten its legs (the hind legs are longer than the forelegs, so its rear end will be higher than its shoulders) and erect the hair along its spine and tail into a ridge to make itself look more impressive. A defensive cat erects not only a ridge of fur, but all of its fur, puffing itself out. It arches its back and positions itself side-on to its aggressor to make itself look larger still. It wants the attacker to think twice about attacking it. If the attacker pauses, the victim may move sideways in a crab-like fashion (frequently seen in playing kittens); it moves slowly away from its aggressor, watching for any sign of attack. The slow retreat is an attempt to avoid provoking a sudden or instinctive attack.
In contrast, a submissive cat wants to appear small and unthreatening. It may shrink into a crouch indicating that it wants only to be left alone. If this doesn't work, it may sink down on one side demonstrating its submissiveness. If the other cat still threatens, the victim will roll over onto its back, turning its head to face its attacker. This is an appeasement gesture. Unlike the dog, which will go belly-up in full submissive mode, a cat on its back is still a formidable opponent. It has done its utmost to avoid conflict, but if the aggressor continues to press the attack, the victim is able to fight back with all four sets of claws and with teeth. Tin this position, if the aggressor jumps on its victim, victim's fore legs can clasp the aggressor close to the victim's teeth. Meanwhile, the hind legs are especially dangerous as they may disembowel the other animal (and are sometimes used in this way against same-size prey such as rabbits which have not been killed outright - something which can be seen when a cat plays with a stuffed toy).
There are other reasons a cat rolls over. A playful cat will roll over in order to use all four paws, claws sheathed, to "defend" itself, sometimes mock-biting the other cat or the owner. Some cats roll over to greet their owners - this is kitten behaviour and an invite for us to "groom" the cat's belly. Unfortunately the kitten behaviour and the adult behaviour often conflict with each other with painful consequences for the owner. Other cats, those with a great degree of trust and affection, love having their bellies rubbed. Oestrus females roll wantonly in front of males to solicit their attention. Cats also roll as a way of scratching their backs, often rolling on hot pavements or in dust-baths.
Nipper in a neutral mood. His whiskers are slightly drooped in relaxation. His ears are in the forward position. His pupils are slitted entirely because of the light. His tail is coiled neatly around him.
Although his ears and whiskers indicate alertness, Tsar's tail is held firmly beneath him in a sign of submissive fear. Tsar had just arrived at a cat shelter and was nervous of his new surroundings.
Shampoo is making a friendly approach towards owner Philip Harvey. Ears and whiskers are pricked forward in interest. Her tail is in the normal horizontal position, but is moving into the friendly upright position.
Not all feline communication or feline behaviour is easily understood, even by those ho are used to cats. We are not attuned to pheromones or to reading the more subtle nuances of their body language. To us, some feline behaviour truly perplexing to the point of bordering on a supernatural explanation. Early one morning in 2002, Michael Powell (Dublin, Ireland) watched 12 cats "of every variety" emerging from a garden across the road from where he stood. The cats pranced across the road in a straight line, nose to tail with their heads and tails up, making a remarkable sight. They gave the distinct impression of being on a mission. When they reached the hedge near to his home, they all turned right in strict formation, took a sharp left through a hole in the hedge, then right again along the side of the hedge, then left at the next corner, right again through another hole in that hedge and out of sight.
Without knowing the familial relationship (if any) of the cats, it is hard to say what was going on. Was the lead cat on oestrus and were the followers her suitors? This seems the most likely explanation. Numerous suitors have been seen trailing after a single oestrus female until she is ready to mate, but rarely in such an orderly fashion. Were the pursuers the grown up offspring of the leader? Kittens will follow their mothers in this way; since domestic cats often retain juvenile behaviour, perhaps this was the case. It brings to mind the curious parade of cats out of an English town some hours before it was bombed during World War II.
On another occasion the same witness saw three cats sitting in the "Egyptian sphynx" position. The centre cat was largest and slightly forward of the other two, both of which were angled slightly away from the centre cat so that they were in an arrow formation. All three cats were staring straight at a fourth cat who was also sitting in the sphynx position directly facing the centre cat. The cats sat like that, motionless and silent for some 10 minutes. It looked like the fourth cat was having an audience with a top cat. Quite possibly this was a boundary dispute with two cats staring each other out over an invisible (to us) territorial boundary. The two smaller cats were probably from the same household as the cat they sat with, shared its territory and were "interested parties" in the dispute.
Linda Louis-VanReed (St Louis, Missouri, USA) had a similar experience of feline follow-the-leader. She adopted a small, black long-haired male cat that stumbled onto her porch in need of urgent medical attention. Though small, Genghis Khan was very dominant and was raised him alongside a labrador/shepherd mix pup. Geenghis was an indoor/outdoor cat and this 8 pound ball of attitude routinely attracted and peacefully dominated every group of local cats he encountered, including aggressive cats, just by sitting down and staring silently. In Orlando, Florida, when Ghengis was 14 years old, Genghis went roaming with Korat kitten Naomi in tow and did not return for several hours, despite Victoria calling for him. The 6 local cats were 14-18 pounds Maine Coon males, two of whom were not neutered. Linda was concerned about Genghis and Naomi because of alligators and snakes in the area. After about 2 and a half hours she called for him again. She says "The hedges next door rustled and out he comes from beneath them, tail up, chest out, looking very calm, like it was any ordinary day. He was followed by his romping little charge, Naomi, and every last one of those large male cats from around the neighborhood, walking in a tight line, all with tails in the same positions, all following within a foot of one another. He lead them about 15 yards or so, until I spoke to him, at which point the others broke formation and ran. He stopped, turned and looked after them, flicked his tail, and strolled in to eat." Genghis lived to 17 and a half and right up to the end he exerted his power of domination/attraction/fascination over other cats.
