Polydactyl cats, known for their unique physical characteristic of having extra toes, have fascinated cat lovers and researchers alike for centuries. The occurrence of polydactyly in cats is a subject of interest, sparking debates about its rarity and the genetic factors that contribute to this trait. In this article, we will delve into the world of polydactyl cats, exploring the genetics behind this phenomenon, the history of polydactyl cats, and the prevalence of polydactyly in feline populations.
Introduction to Polydactyly
Polydactyly is a genetic trait that results in the growth of extra digits on the paws of cats. This condition can occur in varying degrees, ranging from a small, rudimentary extra toe to fully formed, functional digits. Polydactyl cats can have extra toes on one or more paws, and the number of extra toes can vary significantly between individuals. The genetic basis of polydactyly is complex, involving multiple genes that interact to produce the trait.
Genetics of Polydactyly
Research has shown that polydactyly in cats is caused by a dominant autosomal gene, meaning that a cat only needs to inherit one copy of the gene to express the trait. The gene responsible for polydactyly is thought to be related to the HOXD13 gene, which plays a crucial role in limb development. Cats that are homozygous for the polydactyly gene (i.e., they have two copies of the gene) are more likely to have a higher number of extra toes than those that are heterozygous (i.e., they have one copy of the gene).
Types of Polydactyly
There are several types of polydactyly that can occur in cats, including:
Polydactyly can be bilateral, meaning it affects both the left and right paws, or unilateral, affecting only one side. The extra toes can be fully formed, including bones, joints, and claws, or they can be rudimentary, consisting of only a small, soft nub of tissue.
History of Polydactyl Cats
Polydactyl cats have been around for centuries, with evidence of their existence dating back to ancient Egypt. In fact, polydactyl cats were highly valued in Egyptian society, where they were considered sacred animals. The Egyptians believed that polydactyl cats possessed special powers and were often mummified and buried with their owners.
In the United States, polydactyl cats were popularized by Ernest Hemingway, the famous author, who received a polydactyl cat as a gift from a ship’s captain. Today, the Ernest Hemingway Home and Museum in Key West, Florida, is home to a large population of polydactyl cats, many of which are descendants of Hemingway’s original cat.
Prevalence of Polydactyly
So, are polydactyl cats rare? The answer is not a simple yes or no. While polydactyly is not a common trait in most cat breeds, it is more prevalent in certain populations. For example, polydactyly is relatively common in Maine Coon cats, with some studies suggesting that up to 40% of Maine Coon cats have extra toes.
In general, polydactyly is more common in cats of European descent, particularly in the United Kingdom and North America. However, the trait can occur in any breed or mix of breeds, and its prevalence can vary significantly depending on the population being studied.
Factors Affecting Prevalence
Several factors can influence the prevalence of polydactyly in cat populations, including:
- Genetics: As mentioned earlier, the genetic basis of polydactyly is complex, and the interaction of multiple genes can affect the expression of the trait.
- Breed: Certain breeds, such as the Maine Coon, are more likely to have polydactyly due to their genetic makeup.
- Geography: Polydactyly may be more common in certain regions due to the presence of polydactyl cats in the founding population.
- Selection: Breeders may selectively breed for or against polydactyly, affecting its prevalence in certain breeds or populations.
Conclusion
In conclusion, polydactyl cats are not necessarily rare, but their prevalence can vary significantly depending on the population being studied. The genetic basis of polydactyly is complex, and multiple factors can influence its expression. While polydactyly is not a common trait in most cat breeds, it is relatively prevalent in certain populations, such as Maine Coon cats.
Whether you are a seasoned cat breeder or simply a cat enthusiast, polydactyl cats are undeniably fascinating creatures that continue to captivate and inspire us.

For those interested in learning more about polydactyl cats, there are many resources available, including breeders, researchers, and cat registries. By continuing to study and learn about polydactyl cats, we can gain a deeper understanding of their unique characteristics and the genetic factors that contribute to their development.
What is a polydactyl cat?
A polydactyl cat is a cat that has more than the usual number of toes on one or more of its paws. The term “polydactyl” comes from the Greek words “poly,” meaning many, and “dactyl,” meaning finger or toe. Polydactyl cats can have extra toes on their front paws, back paws, or all four paws, and the extra toes can be fully formed and functional or partially formed and non-functional. Polydactyl cats are often referred to as “mitten cats” due to the appearance of their paws.
The genetics behind polydactyly are complex, but it is known that the trait is inherited in an autosomal dominant pattern, meaning that a cat only needs to inherit one copy of the polydactyly gene to express the trait. Polydactyl cats can be found in a variety of breeds, including the Maine Coon, British Shorthair, and Ragdoll, although the trait is not unique to any particular breed. In fact, many polydactyl cats are mixed-breed or domestic shorthairs. Despite their unusual appearance, polydactyl cats are just as loving, playful, and affectionate as any other cat.
How rare are polydactyl cats?
Polydactyl cats are not extremely rare, but they are also not as common as cats with the usual number of toes. The frequency of polydactyly varies depending on the population and breed, but it is estimated that around 1-4% of cats are polydactyl. In some breeds, such as the Maine Coon, polydactyly is more common and may occur in up to 40% of cats. However, in general, polydactyl cats areconsidered to be a relatively rare and unique variation of the typical feline morphology.
The rarity of polydactyl cats is due in part to the fact that many breeders and owners do not consider polydactyly to be a desirable trait. In some cases, polydactyl cats may be at a disadvantage due to their unusual paws, which can make it more difficult for them to perform certain tasks, such as grasping or climbing. However, many polydactyl cat owners and breeders argue that the trait is not a hindrance and that polydactyl cats are just as capable and loving as any other cat. In fact, some owners and breeders actively seek out polydactyl cats for their unique appearance and characteristics.
Do polydactyl cats have any health problems?
Polydactyl cats are generally just as healthy as cats with the usual number of toes, and the extra toes do not typically cause any health problems. However, in some cases, polydactyl cats may be more prone to certain health issues, such as arthritis or injury to the extra toes. This is because the extra toes can be more susceptible to trauma or wear and tear, particularly if they are not properly aligned or if they are subjected to excessive stress.
It is also worth noting that polydactyl cats may be more prone to nail problems, such as ingrown nails or nail overgrowth, due to the extra toes. However, these problems can be easily managed with regular nail trimming and care. In general, polydactyl cats can live long, happy, and healthy lives with proper care and attention. Regular veterinary check-ups and a balanced diet can help to identify and prevent any potential health problems, and many polydactyl cat owners report that their cats are just as energetic and playful as any other cat.
Can polydactyl cats be bred?
Yes, polydactyl cats can be bred, and many breeders actively seek out polydactyl cats for their breeding programs. However, breeding polydactyl cats can be challenging due to the complex genetics behind the trait. Polydactyl cats can inherit the trait from one or both parents, and the expression of the trait can vary widely depending on the genetic makeup of the individual cat. Breeders who specialize in polydactyl cats must carefully select breeding stock and manage their breeding programs to produce healthy, polydactyl offspring.
Breeding polydactyl cats requires a deep understanding of the genetics behind the trait, as well as a commitment to producing healthy and well-socialized kittens. Reputable breeders will prioritize the health and well-being of their cats above any cosmetic considerations, and will work to ensure that their kittens are free from inherited health problems. Polydactyl cat breeders may also be involved in research and conservation efforts to protect and promote the polydactyl trait, which is considered to be an important part of feline diversity and heritage.
Are polydactyl cats more intelligent than other cats?
There is no scientific evidence to suggest that polydactyl cats are more intelligent than other cats. Intelligence is a complex trait that is influenced by a variety of genetic and environmental factors, and it is not directly related to the number of toes a cat has. Polydactyl cats are just as capable of problem-solving, learning, and adapting to their environment as any other cat, but their intelligence is not necessarily enhanced by their extra toes.
That being said, many polydactyl cat owners and breeders report that their cats are highly intelligent and resourceful, and that they are able to adapt quickly to new situations and challenges. This may be due to the fact that polydactyl cats are often highly curious and playful, and are motivated to explore and investigate their surroundings. However, it is essential to remember that every cat is an individual, and that intelligence and personality are influenced by a wide range of factors, including genetics, environment, and socialization.
Can I get a polydactyl cat as a pet?
Yes, you can get a polydactyl cat as a pet, and many people find that polydactyl cats make wonderful and loving companions. Polydactyl cats are available from a variety of sources, including breeders, rescue organizations, and shelters. If you are interested in getting a polydactyl cat, it is essential to do your research and find a reputable breeder or rescue organization that prioritizes the health and well-being of their cats.
When getting a polydactyl cat as a pet, it is essential to consider the needs and requirements of the individual cat, rather than just its appearance. Polydactyl cats require the same care and attention as any other cat, including regular veterinary check-ups, a balanced diet, and plenty of exercise and playtime. With proper care and attention, polydactyl cats can thrive and make wonderful pets for people who are looking for a unique and loving companion. Additionally, many polydactyl cat owners report that their cats bring a special kind of joy and charm to their lives, and that they are well worth the extra attention and care.
