Do Rabbits And Cats Mate? No, cats and rabbits cannot mate and produce offspring. They are different species with incompatible genetics. Visit solcat.net for reliable information about feline genetics and behavior. Let’s debunk the cabbit myth!
1. Understanding the Impossibility of Cat-Rabbit Hybrids
Can a cat and rabbit procreate? The idea of a “cabbit,” a hybrid of a cat and a rabbit, has been circulating for years, fueled by folklore, anime, and the desire to believe in extraordinary creatures. However, from a scientific standpoint, the cabbit is nothing more than a myth. Cats and rabbits are simply too different genetically to produce viable offspring.
1.1 Genetic Incompatibility
Cats and rabbits belong to different biological families, carnivores and lagomorphs, respectively. Their genetic makeup is vastly different. Cats have 38 chromosomes, while rabbits have 44. For successful hybridization to occur, the parent species need a high degree of genetic similarity, which is simply not the case with cats and rabbits.
1.2 Digestive System Differences
Cats are obligate carnivores, meaning their bodies are designed to digest meat. They have short digestive tracts optimized for processing animal protein and fat. Rabbits, on the other hand, are herbivores with long digestive systems adapted to break down plant matter. Their bodies produce an enzyme called cellulase to digest cellulose, a component of plant cell walls. The digestive systems of cats and rabbits are so different that even if a cat consumed the same food as a rabbit, it would not be able to extract the necessary nutrients.
Here’s a table summarizing the digestive system differences between cats and rabbits:
| Feature | Cat | Rabbit |
|---|---|---|
| Diet | Obligate carnivore | Herbivore |
| Stomach | Medium size | Large |
| Small Intestine | Short, relatively wide | Long |
| Caecum/Appendix | Poorly developed/vestigial | Medium to large size |
| Large Intestine | Short | Medium |
| Stools | Moist, foul-smelling | (1) soft, re-ingested (2) dry, compact, odorless |
1.3 Mating and Gestation Differences
Even the mating habits of cats and rabbits are incompatible. Female cats are induced ovulators, meaning they release eggs only after being stimulated by the barbs on a male cat’s penis during mating. Male rabbits lack these barbs, so even if a rabbit were to mate with a female cat, it wouldn’t trigger ovulation.
Furthermore, the gestation periods of cats and rabbits are significantly different. Rabbits gestate for about 30-31 days, while cats gestate for about 63 days. This difference in gestation time makes it impossible for a hybrid embryo to develop to term.
1.4 Chromosomal Differences
All but 4 of the cat species have 19 pairs of chromosomes while the rabbit has 22 pairs (38 chromosomes in cats, 44 in rabbits). The South American Geoffroy’s Cat, Oncilla, Margay and Ocelot all have 18 pairs due to a fusion of two chromosomal pairs. Only genetically similar animals (same number of chromosomes) can hybridize. The gestation period of the rabbit is 30-31 days. The gestation period of the domestic cat is approximately 63 days. This is not a “similar gestation period” – the cat’s gestation period is double that of the rabbit.
A domestic cat and a rabbit are together, highlighting their physical differences that contribute to their genetic incompatibility.
2. Debunking Common Cabbit Myths
Despite the scientific evidence against their existence, the cabbit myth persists. Let’s address some of the most common misconceptions:
2.1 “My Cat Had Kittens That Looked Like Rabbits”
Sometimes, kittens are born with physical deformities that make them resemble rabbits. For example, kittens with Manx syndrome may have shortened spines and hind legs, causing them to hop instead of walk. These deformities are due to genetic mutations or developmental abnormalities, not hybridization with a rabbit.
2.2 “I Saw a Cabbit on TV”
In 1977, an animal described as a cabbit appeared on the Johnny Carson show. However, zoologists later examined the animal and determined it was simply a cat with a pelvic deformity. This incident highlights how easily people can be misled by appearances.
2.3 “Cabbits Are Common in My Area”
Some people claim that cabbits are common in certain regions. Such claims are often based on anecdotal evidence and misidentification of animals with deformities or unusual features. There is no credible evidence to support the existence of cabbits in any part of the world.
3. Barriers to Hybridisation Explained
Let’s look at the natural mechanisms for keeping species separate:
- Physical/geographical separation. There is no physical separation; cats and rabbits can be found in the same regions. In the wild, cats would normally regard rabbits as prey, but in domestic settings there have been numerous observed mating between cats and rabbits. These have been matings in both directions i.e. buck rabbit and female cat, or tomcat and female rabbit. No pregnancies resulted. A number of misguided individuals have attempted to breed cabbits and, encouraged by anime and folklore, continue to do so, often with disastrous results for the rabbit when the cat’s predatory instinct prevailed. So, although habitats may overlap, these are not hybridisation zones as there is no evidence of hybrids occurring.
- Temporal isolation.. Both species can be on heat/in breeding condition at the same time of year so there is no temporal (time/season) isolation from each other.
- Behavioural isolation. In the wild, the cat and rabbit would be deterred from mating because of their differing behaviours – the rabbit would act as a prey animal and the cat would act as a predator. In a household, where cats and rabbits can coexist amicably, matings have been observed. So, there is not behavioural isolation in all habitats.
- Mechanical isolation. This would mean that the size and conformation of the two species genitalia would make copulation impossible. Cat and rabbit genitalia suggest that penetration is possible.
- Morphological isolation. This would mean the size and conformation of the individuals prevent copulation. Cats and rabbits are similarly sized. In fact, far greater size differences have been overcome such as a male ocelot impregnating a female puma three times his size, and a male seal successfully copulating with a penguin.
The previous 5 barriers are, it turns out, not barriers in the case of cats and rabbits in a domestic setting. The lack of any physical cabbit progeny indicates that the 6th barrier prevents it:
- Gametic isolation. The sperm and egg may not fuse and hence fertilization cannot occur; or if fertilization does occur then the embryo fails to get past the first few cell division. If the layer surrounding the ovum does not bind with the sperm (because the proteins on the head of the sperm are not compatible), the sperm can’t get inside the obvum to fertilise it. That leaves only one other option: in vitro (test tube) methods that fuse the gametes. There is still no guarantee that the egg would get beyond the first several cell divisions to form an embryo. Making such hybrids are not high on the priority list of scientists.
4. The Role of Genetic Engineering
While natural hybridization between cats and rabbits is impossible, some people wonder if genetic engineering could make it a reality.
4.1 Hybridomas: A Glimmer of Hope?
Scientists have created hybridomas by fusing cells from different species. Hybridomas are cells formed by fusing a normal cell with a tumour cell to create a hybrid cell which can multiply in the laboratory, but which cannot build a whole new creature. After the cells fuse, the hybridoma randomly ejects its redundant chromosomes.
Researchers have successfully made mouse/rat hybridomas (both are rodents) and have tried more exotic combinations. The closest they have come to a cabbit is a rabbit/hamster hybridoma (lagomorphs and rodents are closely related).
4.2 The Challenges of Creating a Cabbit Through Genetic Engineering
Even with advanced genetic engineering techniques, creating a viable cabbit would be incredibly challenging. It would require overcoming numerous genetic incompatibilities and manipulating the development of the embryo in ways that are currently beyond our capabilities. Michael Onken of the MadSci Network writes that there has never been a successful cross between a cat and a rabbit. The production of a hybrid mammal requires a great deal of genetic sameness (not just similarity) between both parents and even then the offspring are often sterile or stillborn. A viable cross between creatures as different as a cat (carnivore) and rabbit (lagomorph) is impossible without extensive genetic engineering. That sort of genetic engineering is still decades away. The closest modern science has come to this is with “hybridomas”.
Furthermore, even if a cabbit could be created, it’s likely to suffer from severe health problems and a shortened lifespan. The ethical implications of creating such a creature would also need to be carefully considered.
5. Why the Cabbit Myth Persists
If cabbits are scientifically impossible, why does the myth persist? Several factors contribute to its enduring popularity:
5.1 The Desire for the Extraordinary
People are naturally drawn to the idea of unusual and fantastic creatures. The cabbit combines the familiar features of cats and rabbits into a novel and intriguing animal, appealing to our sense of wonder.
5.2 Cultural Influences
Cabbits have appeared in various forms of popular culture, including anime and folklore. These depictions often portray cabbits as cute and whimsical creatures, further fueling the myth.
5.3 Misinformation and Hoaxes
The internet is rife with misinformation, and the cabbit myth is no exception. Fake photos, fabricated stories, and deliberate hoaxes contribute to the spread of false information about cabbits.

6. Understanding Animal Hybridization
Although cats and rabbits cannot interbreed, hybridization does occur in the animal kingdom. It’s crucial to understand the limitations and conditions under which hybridization is possible.
6.1 Closely Related Species
Hybridization is most likely to occur between closely related species, meaning those that share a recent common ancestor. For example, wolves and dogs can interbreed because they are both members of the Canis genus.
6.2 Chromosome Number and Structure
Species that can hybridize usually have similar chromosome numbers and structures. This allows the chromosomes from each parent to pair up correctly during meiosis, the process that produces sperm and egg cells.
6.3 Viability and Fertility of Hybrids
Even when hybridization does occur, the offspring are not always viable or fertile. Hybrids may inherit incompatible genes or developmental abnormalities that prevent them from surviving or reproducing. Mules, the offspring of horses and donkeys, are a classic example of infertile hybrids.
7. Common Misconceptions About Animal Breeding
Many misconceptions exist about animal breeding, especially when it comes to the possibility of creating hybrids between distantly related species.
7.1 The “Anything Can Mate With Anything” Fallacy
Some people believe that any two animals can mate and produce offspring, regardless of their species. This is simply not true. As we’ve seen with cats and rabbits, genetic and biological barriers prevent hybridization between distantly related species.
7.2 The “If They Mate, They’ll Have Babies” Myth
Just because two animals mate doesn’t mean they’ll produce offspring. Successful reproduction requires fertilization, proper embryonic development, and a viable pregnancy. Any of these steps can be disrupted by genetic incompatibilities.
7.3 The “It Happened to My Friend’s Animal” Anecdote
Anecdotal evidence is not a reliable source of information about animal breeding. Stories about “cabbits” or other impossible hybrids are often based on misidentification, misinformation, or outright fabrication.
8. The Importance of Reliable Information
In the age of the internet, it’s more important than ever to rely on credible sources of information, especially when it comes to science and animal biology.
8.1 Consulting Experts
When you have questions about animal breeding or genetics, consult with qualified experts, such as veterinarians, zoologists, and geneticists. These professionals have the knowledge and experience to provide accurate and reliable information.
8.2 Checking Scientific Sources
Look for information from reputable scientific journals, textbooks, and websites. These sources undergo peer review, ensuring that the information is accurate and up-to-date.
8.3 Avoiding Misinformation
Be wary of information from unreliable sources, such as social media, blogs, and websites that promote pseudoscience or conspiracy theories. Always double-check information before accepting it as fact.
9. Understanding Manx Cats
One of the primary reasons people believe they’ve seen a ‘cabbit’ is often linked to the unique characteristics of Manx cats. These cats possess a natural genetic mutation that affects their spine, leading to a shortened or absent tail. This genetic anomaly can sometimes cause them to move with a hopping gait similar to rabbits, further fueling the cabbit myth. However, it’s crucial to understand that Manx cats are entirely feline and not a hybrid species.
9.1 Distinguishing Features of Manx Cats
The most distinctive feature of Manx cats is, of course, their lack of a tail. However, this breed also has several other traits, including a round back, short body, and long hind legs, which can contribute to their rabbit-like appearance.
9.2 The Manx Gene and Its Effects
The Manx gene, responsible for the breed’s unique characteristics, is a dominant gene. However, if a kitten inherits two copies of the Manx gene, it can lead to severe spinal deformities and even death.
