DOMESTIC X ONCILLA AND BLACK FOOTED CAT HYBRIDS
DOMESTIC X ONCILLA HYBRIDS
F. tigrina, the Tiger Cat (Little Spotted Cat/Oncilla) can interbreed although most offspring are stillborn and meetings between Tiger Cats and domestic cats normally resulted in the death of the domestic cat due to the Tiger Cat's highly aggressive nature. Paul Leyhausen reported successful matings between a male Oncilla and a female domestic cat. Out of seven kittens born, three were stillborn. However, the Oncilla male was notably aggressive towards female Oncillas and it also killed a domestic female much larger than itself.
Long Island Ocelot Club newsletters of November/December 1964, May/June 1966 and May/June 1968 carried reports of the Oncilla/domestic hybrids bred in Arnhem, The Netherlands by Maria Falkena-Rohrle. The 6-8 lb Oncilla was also known as the "dwarf ocelot". As well as studying oncilla family behaviour, Mme Falken Rohrle was attempting to cross Oncillas with Margays. She had raised the Oncillas alongside domestic Abyssinians in order to make them better housepets. She was mating a female oncilla called Candy to an oncilla male called Milagro. Falkena-Rohrle wrote that Dr Zimmerman in Mt Vernon had been most helpful when Candy was expecting her first litter and again when Iris, an Abyssinian domestic cat, had her litter of oncilla hybrids.
Iris had been calling, but Falkena-Rohrle did not want her to have another litter and kept her separated from the male Abyssinians, but forgot that oncilla stud Milagro might be interested in the much larger domestic cat. She observed Milagro mating with Iris, but was assured the mating would result in nothing but dead kittens if it resulted in anything at all. One authority said that the Oncilla, belonging to the ocelot group had a different number of chromosomes than the domestics and the pair could not breed. When Iris appeared to be pregnant, the owner expected nothing more than a dead kitten and 61 days after the mating she found a dead kitten in Iris's basket, soon followed by another stillborn kitten. Two hours later a live kitten was born and the birth was also witnessed by Mrs Ewer, a well known zoologist from Ghana who was visiting Falkena-Rohrle to to see the cats.
The kitten developed nicely, "not troubling herself about chromosomes and things", and looked more and more like the oncilla sire as she grew. Falkena-Rohrle named her Gloria and she grew up in the care of two Abyssinian mothers whose four male kits were born a few hours before Gloria. It was extremely interesting compare the development of Gloria with Candy's pure-bred oncilla kittens (Victor and Victoria). The two dead hybrid kittens were shipped at the request of Falkena-Rohrle's veterinarian to a friend who is a professor in a Texas university who wished to study the chromosomes of feline hybrids.
According to some reports, Mme Falken-Rohrle was intrigued as to whether the kitten, named "Gloria" was a hybrid or a mutation of the Abyssinian so she deliberately bred an Abyssinian male to an Oncilla female resulting in three more hybrids. It appears from the LIOC newsletters that by 1966, Milagro (oncilla male) and Iris (Abyssinian) had produced three living hybrids which received wide acclaim in European feline fanciers' circles, and abroad in "CATS", a USA magazine as "Glowca, Gloria and Glamour, famed oncilla-abysinnian hybrid trio". Milagro had had to be defanged after killing an older - and larger - female cat, Snoesje, through a bite to the neck.
The Oncilla has two chromosomes fewer (36) than the domestic cats (38), explaining why the Oncilla-Abyssinian hybrids - all female - had all been sterile and possibly why none of the male hybrids had survived. Although the two species were able to produce hybrids, there appears to have been enough mismatch that both sexes were sterile rather than only the males being sterile. The comparable case of the Safari breed (Geoffroys x domestic), with a similar mismatch, results in sterile males and some fertile females.
The Oncilla-Abyssinian hybrids were described by Leyhausen and Falkena as "very beautiful". Their coats had three longitudinal stripes down the back and the rest was patterned with small spots partly arranged into rosettes. The tails were ringed with a number of black hoops. The tail-tip was black.
According to the Long Island Ocelot Club newsletter of September/October 1981, Leyhausen kept a number of oncillas and bred them, comparing their behaviour to that of other small wildcats as well as to domestic cats. Together with a German cat breeder, Maria Falkena-Rohrle, Leyhausen successfully hybridized oncillas with domestic cats.

Following are excerpts from "Abyssinian x Wild Cat by Maria Falkena (Holland)", published in "Our Cats", August 1965. These provide further details about the appearance and behaviour of the hybrids.
"Two young cats, spotted in the way ocelots are; four very small cats, one of them six months old, the other three about ten weeks - these are the kittens I write about today. In November 1963 we were given the opportunity to purchase an oncilla male, probably the only one in captivity. We christened him "Milagro", which is the Spanish term for "wonder," and judged him to be about 8 months old. In the following spring he mated Candy (an oncilla) and the result was an undersized kitten which only lived three days. A second mating produced two little oncilla babies.
The other four [kittens] are hybrids. The father is Milagro, the oncilla male, and the mother Iris, an Abyssinian female. The first mating of this sort took place accidentally and we did not expect anything more than dead kittens as we had been informed that cats of the ocelot group [i.e. ocelot, margay, oncilla] were too far away from our domestic cat for any mating to be successful. News of the birth of the "impossible cat" was broadcast and written up by an illustrated journal. We called this first hybrid kitten Gloria and of course we looked after her most carefully. In appearance and behavour Gloria holds the middle between her wild ancestors and the Abyssinians. her movements are quicker and more spontaneous. She refuses other food than meat, like the oncillas do, but will also eat it boiled, which the oncillas will not. She has a long lean body and her head and the texture of her coat are definitely those of her father. From him she has inherited the warm brown eyes and the round ears with the white spot inside. But the spots are much smaller than Milagro's, all very close and neatly arranged.
A second mating between Milagro and Aurelia, another Aby female, produced three more hybrids, all looking and behaving like Gloria; all females. The mother is just as proud and happy with them as any queen with her kittens. Now and again it appears she does not quite understand the different voice which her babies have. As they develop and Aurelia's interest fades as they reach the age when Aby kittens are self-supporting, the attachments of the little hybrids becomes directed more towards me. When I enter and speak to them, they will wake up and roll up into a ball in the true oncilla fashion. This is a funny sight, especially to strangers.
My hybrids have lost the habit which unfortunately the oncilla has got - they do not spray. They are not so nervous but they have not kept the attractive markings of the wild cat. We might get the spots back by crossing the hybrids back to Milagro - that is, of course, they are fertile hybrids. Ever since I have bred the hybrids, many requests have come in for them, also requests for Milagro to be allowed to mate Siamese and Havanas. I would not entertain any of them. What a mixture I should be responsible for in the Fancy is unlimited crossing with wild cats were encouraged? Perhaps her response would have been different in the 1990s as various wild cat hybrids were being developed and Pandora's box has been well and truly opened. Crossing an oncilla to a spotted tabby would likely have preserved the spots in the hybrids. I suspect the end result would have been similar to the modern Bengal.
DOMESTIC X BLACK-FOOTED CAT HYBRIDS
The Black-footed cat (F. nigripes) will breed with both domestic cats and F. lybica, fertility of offspring is not recorded. The Black-footed cat (F nigripes) is considered one of the most unsociable cats. Contact between the two sexes reduced to an absolute minimum and occurs only when breeding. Paul Leyhausen successfully bred Black-footed cats in captivity and had no difficulty in mating his Black-footed cats with domestic cats. In the wild, they are reliably reported to interbreed with caffer cats (the South African form of the African wildcat).
