It is not possible. You can only breed between species if there is some degree of genetic compatibility. Rabbits and cats are not only different species they are different genera as well.
A cabbit is a fictional hybrid between a cat and a rabbit. They have appeared in fiction and fantasy stories including Japanese anime and manga, and have also been dubiously claimed to have been observed in the wild. Most if not all observations are attributable to either misidentified Manx cats or outright hoaxes.
As far as the humping, it's normal for a rabbit to hump things for dominance.
The most common interspecies breeds are the Bengal (domestic cat x Asian leopard cat [ALC], Prionailurus bengalensis), Savannah (Domestic cat x African serval, Profelis serval), and Chausie (Domestic cat x Jungle cat, Felis chaus).
Your cat will back off or get away from the rabbit if feeling comfortable. Keep in mind that if your rabbit runs, your cat may see the rabbit as prey and chase him. If that happens, separate the animals immediately and begin the process of introducing them over again, going more slowly this time.
Among domestic animals rabbits and dogs are both among the most promiscuous in their choice of mate. Indeed, both will attempt to mate even with various types of birds, as documented in YouTube videos.
Contrary to popular belief, rabbits and cats and even dogs can make great pet companions. Although these prey-predator combinations seem like they're defying the course of nature, it's in fact a very common and rewarding relationship.
But creating hybrids of animals that are very genetically distinct from each other—such as a dog and a cat—is scientifically impossible, as is one species giving birth to an entirely different one. That has not stopped people from hoping.
A little known fact is that kittens in a single litter can have different fathers. There could even be as many fathers as there are kittens! The ability to produce a litter of kittens fathered by more than one tom cat is called superfecundation.
It is a show of dominance and territoriality. Get your rabbit neutered if he isn't - this will greatly reduce, maybe completely stop, the behavior.
Why does my rabbit put her head down when I pet her? When your rabbit lays their head down flat on the ground, they are enjoying being pet and are laying still so that you continue. They might even close their eyes or nudge your hand if you stop petting them.
Your rabbit does this as a way of asking for attention. They want you to play with them, pet them, or interact with them.
Unlike most pet dogs, which come from a mixture of purebreed lineages, cats started as a mixture of many wildcat variations and have been selectively bred by humans for certain traits that lead to modern breeds. This has allowed for a large increase in the number of breeds in a shorter amount of time.
Small breeds (such as the Polish) can be bred at 4 to 5 months of age. Medium breeds (for example New Zealands and Californians) become sexually mature at 6 to 7 months of age. The giant breeds (such as the Flemish Giant) should be at least 7 months of age when bred.
Jackalopes are not a distinct species of rabbit, they simply are cottontails and jackrabbits afflicted with a rare virus.
Avoid inbreeding: Breeding from closely related cats such as brother and sister, mother and son or father and daughter, grandfather and granddaughter, predispose kittens to genetic problems or birth defects.
A dog cannot impregnate a cat because they are not the same species or genus. Dogs are a species called Canis familiaris. Domestic cats are a species called Felis catus in Latin.
Can Male Cats Sense Pregnancy? Yes- male cats are able to detect pregnancy (or, more specifically, the changes in your body due to pregnancy) just like female cats can!
Why Is My Dog Humping My Cat? If your dog humps your cat, it may be a sign of excitement or part of play, if the two pets do usually play with each other. Some small dogs may mount a cat if there is social conflict between them.
Surprisingly, a domestic cat and a bobcat cannot produce viable offspring despite their similar appearances. While some rumors suggest that there are mixed hybrid bobcats, this is false. There is no scientific evidence that points to this possibility since they have such different reproductive systems.
Male dogs have homosexual sex under a variety of circumstances. They mount each other in dominance displays, and that mounting can involve anal penetration. (This is probably what happened in Tennessee if, in fact, there was even sex involved.)
If the rabbit and cat are of similar size, or if the rabbit is bigger, then the rabbit is quite capable of defending itself. But an adult cat can easily harm or kill a smaller bunny, especially a baby.
Once it feels comfortable enough, a rabbit can be dominant, even aggressive, in some cases towards a cat. Consequently, if the cat is more docile and timid by nature, don't get surprised if you notice your bun bossing around.
Rabbits have sensitive airway passages and the dust form clay litter can cause a lot of problems. Instead, ensure that the cat box is in a place only accessible to the cats and not the rabbits. In contrast, indoor cats with low exposure to outside animals (like mice), are much less likely to be worm egg carriers.
