As a cat owner, you may have noticed that your feline friend has an unusual number of toes, with some cats having as many as six or more toes on each paw. This condition is known as polydactyly, and it’s more common than you might think. But what causes polydactyly in cats, and is it a cause for concern? In this article, we’ll delve into the world of feline polydactyly, exploring the history, genetics, and implications of this fascinating phenomenon.
Understanding Polydactyly
Polydactyly is a genetic trait that affects cats, causing them to have extra toes. The condition can occur in any breed or mix of breeds, although it’s more common in certain breeds such as the Maine Coon or the British Shorthair. Polydactyly can manifest in different ways, with some cats having only one or two extra toes, while others may have multiple extra toes on each paw.
The Genetics of Polydactyly
Research has shown that polydactyly in cats is caused by a dominant autosomal gene, which means 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 linked to the PD gene, which codes for a protein involved in limb development. When the PD gene is mutated or duplicated, it can lead to the formation of extra toes.
The Role of Ernest Hemingway
One of the most famous examples of polydactyl cats is the descendants of Ernest Hemingway’s cats, which still roam the grounds of his former home in Key West, Florida. Hemingway, a renowned author and cat lover, was given a white, six-toed cat named Snowball by a ship’s captain. Over time, Snowball’s descendants interbred, resulting in a colony of polydactyl cats that have become a popular tourist attraction.
The History of Polydactyly in Cats
Polydactyly has been observed in cats for centuries, with records of six-toed cats dating back to ancient Egypt. In those days, polydactyl cats were highly valued for their unique appearance and were often considered to be good luck charms. In the Middle Ages, polydactyl cats were sought after by sailors, who believed that the extra toes brought good fortune and protection from evil spirits.
Polydactyly in Different Breeds
While polydactyly can occur in any breed or mix of breeds, some breeds are more prone to the condition than others. The Maine Coon breed, for example, has a high incidence of polydactyly, with some studies suggesting that up to 40% of Maine Coon cats have extra toes. Other breeds, such as the British Shorthair and the Ragdoll, also have a higher than average incidence of polydactyly.
Health Implications of Polydactyly
While polydactyly is generally considered to be a harmless condition, there are some potential health implications that cat owners should be aware of. For example, extra toes can be prone to injuries, such as torn nails or cuts, and may require additional grooming to prevent matting and tangling. In rare cases, polydactyly can also be associated with other genetic conditions, such as radial hypoplasia, which affects the development of the radius bone in the forearm.
Caring for a Polydactyl Cat
If you’re the proud owner of a polydactyl cat, there are a few things you can do to ensure that your cat stays happy and healthy. Here are a few tips:
- Provide regular grooming to prevent matting and tangling of the extra toes
- Keep an eye out for injuries, such as torn nails or cuts, and seek veterinary attention if necessary
- Consider providing a scratching post or pad to help keep your cat’s nails trimmed and healthy

What is polydactyly and how does it affect cats?
Polydactyly is a congenital anomaly that causes cats to be born with extra toes. The term “polydactyly” comes from the Greek words “poly,” meaning “many,” and “dactyl,” meaning “finger” or “toe.” This condition is relatively common in cats, and it can occur in any breed or mix of breeds. Polydactyly is usually harmless, but it can occasionally cause problems for cats, such as difficulty walking or an increased risk of injury to the extra toes.
In cats, polydactyly typically manifests as extra toes on the front paws, although it can also occur on the back paws. The extra toes are usually smaller than the normal toes and may or may not have claws. Some cats with polydactyly may have only one extra toe, while others may have multiple extra toes on each paw. The condition is usually inherited, and breeders may intentionally breed cats with polydactyly to create kittens with this unique characteristic. Overall, polydactyly is a fascinating and relatively harmless condition that can add to a cat’s charm and individuality.
How common is polydactyly in cats, and are certain breeds more prone to it?
Polydactyly is a relatively common condition in cats, and it can occur in any breed or mix of breeds. However, some breeds are more prone to polydactyly than others. The Maine Coon breed, for example, is known for its high incidence of polydactyly, and many breeders intentionally breed Maine Coon cats with this characteristic. Other breeds, such as the British Shorthair and the Ragdoll, may also have a higher incidence of polydactyly.
Studies have shown that polydactyly is more common in certain geographic regions, particularly in the northeastern United States and Canada. This is likely due to the fact that many of the foundation cats used to develop the Maine Coon breed, which is prone to polydactyly, came from these regions. Additionally, polydactyly may be more common in feral cat populations, as these cats are more likely to have inherited the trait from their ancestors. Overall, while polydactyly can occur in any breed or mix of breeds, certain breeds and geographic regions may be more prone to this condition.
Is polydactyly a genetic condition, and can it be inherited?
Yes, polydactyly is a genetic condition, and it can be inherited from a cat’s parents. The condition is usually caused by a dominant autosomal gene, which means that a cat only needs to inherit one copy of the gene to express the condition. If a cat inherits two copies of the gene, one from each parent, it is likely to have a more severe form of polydactyly, with multiple extra toes on each paw.
The genetics of polydactyly are complex, and multiple genes may be involved in the development of this condition. However, research has identified a single gene, called the ZRS gene, that plays a key role in the development of polydactyly. This gene is responsible for regulating the expression of other genes involved in limb development, and mutations in the ZRS gene can lead to the formation of extra toes. Breeding cats with polydactyly can be challenging, as the condition can be difficult to predict and may not always follow a simple inheritance pattern.
Can polydactyly cause health problems in cats?
In most cases, polydactyly is a harmless condition that does not cause any health problems for cats. However, in some cases, polydactyly can lead to complications, such as difficulty walking or an increased risk of injury to the extra toes. Cats with polydactyly may also be more prone to arthritis or other joint problems, particularly if the extra toes are not properly aligned or are putting additional stress on the joints.
If a cat with polydactyly experiences health problems related to the condition, treatment will depend on the specific issue. For example, if a cat is having trouble walking due to the extra toes, a veterinarian may recommend surgery to remove the affected toes. In other cases, a veterinarian may recommend conservative treatment, such as pain management or physical therapy, to help manage the condition. Regular veterinary check-ups are essential to monitor the health of cats with polydactyly and to address any potential problems early on.
How is polydactyly diagnosed in cats?
Polydactyly is usually diagnosed in cats at birth or shortly after, as the extra toes are typically visible on physical examination. A veterinarian may also use radiographs (x-rays) or other imaging tests to confirm the diagnosis and to evaluate the alignment and structure of the extra toes. In some cases, a veterinarian may recommend genetic testing to determine the underlying cause of the condition and to predict the likelihood of passing it on to offspring.
If a cat is diagnosed with polydactyly, a veterinarian will usually recommend regular monitoring to ensure that the condition is not causing any health problems. This may include regular check-ups, radiographs, and other diagnostic tests to evaluate the condition and to address any potential issues early on. In some cases, a veterinarian may also recommend consulting with a veterinary specialist, such as a surgeon or a geneticist, to discuss the best course of treatment and to address any concerns.
Can polydactyly be treated or corrected in cats?
In most cases, polydactyly does not require treatment, as it is a harmless condition that does not cause any health problems for cats. However, in some cases, a veterinarian may recommend surgery to remove the extra toes, particularly if they are causing difficulty walking or are at risk of injury. Surgery is typically performed under general anesthesia and may involve removing one or more of the extra toes, depending on the severity of the condition.
The decision to treat polydactyly with surgery should be made on a case-by-case basis, taking into account the individual cat’s needs and circumstances. A veterinarian will typically discuss the potential benefits and risks of surgery with the cat’s owner and recommend the best course of treatment. In some cases, a veterinarian may also recommend conservative treatment, such as pain management or physical therapy, to help manage the condition and improve the cat’s quality of life. Ultimately, the goal of treatment is to ensure the cat’s comfort and well-being, while also addressing any potential health problems related to the condition.
Are cats with polydactyly more prone to other genetic disorders?
Cats with polydactyly may be more prone to other genetic disorders, particularly those that affect the development of the limbs or the skeletal system. For example, cats with polydactyly may be more likely to have other congenital anomalies, such as syndactyly (fused toes) or ectrodactyly (split toes). Additionally, some studies have suggested that cats with polydactyly may be more prone to certain genetic disorders, such as hypertrophic cardiomyopathy (a heart condition) or patellar luxation (a kneecap disorder).
However, it is essential to note that the relationship between polydactyly and other genetic disorders is complex and not fully understood. More research is needed to determine the extent to which polydactyly may increase the risk of other genetic disorders in cats. If a cat is diagnosed with polydactyly, a veterinarian may recommend genetic testing or other diagnostic tests to evaluate the cat’s overall health and to identify any potential genetic disorders. By working closely with a veterinarian, cat owners can help ensure the best possible health and well-being for their feline companions.
