The feline world is filled with wonders and curiosities, and one of the most intriguing aspects of cat anatomy is the occurrence of extra toes. Polydactyly, a genetic trait that causes cats to have more than the usual number of toes, has fascinated cat enthusiasts and scientists alike for centuries. But what happens if a cat has 6 toes? Is it a sign of good luck, a genetic defect, or simply a unique characteristic? In this article, we will delve into the world of polydactyly, exploring its causes, effects, and significance in the feline realm.
Understanding Polydactyly
Polydactyly is a congenital anomaly that affects cats, causing them to have extra toes on one or more of their paws. The term “polydactyly” comes from the Greek words “poly” meaning “many” and “dactyl” meaning “finger” or “toe”. This condition is relatively common in cats, with some breeds being more prone to it than others. The most common form of polydactyly in cats is having an extra toe on the front paws, known as preaxial polydactyly.
The Genetics of Polydactyly
Polydactyly 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 believed to be linked to the production of a protein called fibroblast growth factor 8 (FGF8), which plays a crucial role in the development of limbs and digits. Research suggests that polydactyly is a result of a mutation in the FGF8 gene, which leads to an abnormal expression of the protein and subsequent formation of extra toes.
Types of Polydactyly
There are several types of polydactyly, each with its unique characteristics and effects on the cat’s anatomy and behavior. The most common types of polydactyly include:
Preaxial polydactyly: This is the most common form of polydactyly, where the extra toe is located on the front paws.
Postaxial polydactyly: This type of polydactyly occurs when the extra toe is located on the back paws.
Mesaxial polydactyly: This rare form of polydactyly occurs when the extra toe is located in the middle of the paw.
The Effects of Polydactyly on Cats
So, what happens if a cat has 6 toes? The effects of polydactyly on cats can vary depending on the severity and location of the extra toes. In general, polydactyly does not cause any significant health problems or disabilities in cats. However, in some cases, the extra toes can lead to:
Increased Grip and Balance
Cats with polydactyly often have an advantage when it comes to grip and balance. The extra toes provide additional traction, allowing them to climb and jump with greater ease and agility. This is especially beneficial for cats that are prone to climbing or jumping, as it reduces the risk of falls and injuries.
Improved Dexterity
Polydactyl cats often exhibit improved dexterity, as the extra toes allow them to manipulate objects with greater precision. This can be particularly useful for cats that enjoy playing with toys or hunting small prey.
Potential Drawbacks
While polydactyly can have its advantages, there are also some potential drawbacks to consider. For example, cats with polydactyly may be more prone to nail problems, as the extra toes can lead to increased nail growth and wear. Additionally, polydactyl cats may require more frequent grooming to prevent matting and tangling of the fur around the extra toes.
Breeds and Polydactyly
Some cat breeds are more prone to polydactyly than others. The Maine Coon breed, for example, is known for its high incidence of polydactyly, with some studies suggesting that up to 40% of Maine Coon cats have extra toes. Other breeds that are prone to polydactyly include the British Shorthair and the Ragdoll.
History and Significance
Polydactyly has a long and fascinating history, with many cultures and societies attributing mystical and symbolic significance to cats with extra toes. In ancient Egypt, for example, cats with polydactyly were considered to be sacred animals, with the extra toes believed to symbolize good luck and prosperity. In some modern societies, polydactyl cats are still considered to be good luck charms, with many people believing that they possess unique spiritual and mystical powers.
Conclusion
In conclusion, having 6 toes is not a cause for concern for cats, and in many cases, it can even be beneficial. Polydactyly is a unique and fascinating trait that can provide cats with improved grip, balance, and dexterity.

What is polydactyly in cats and how common is it?
Polydactyly is a genetic trait that causes cats to have extra toes. Normally, cats have five toes on their front paws and four toes on their back paws. Polydactyl cats, however, can have as many as seven toes on each paw. This condition is relatively rare, but it’s more common in certain breeds, such as the Maine Coon. Polydactyly is usually inherited from parents, but it can also occur spontaneously due to genetic mutations.
The frequency of polydactyly varies depending on the breed and population of cats. In general, about 1-4% of cats have polydactyly, but this number can be higher in certain breeds. For example, a study found that about 40% of Maine Coon cats have polydactyly. Polydactyly can occur in any cat, regardless of breed or mix, and it’s often associated with other genetic traits, such as larger size and distinctive coat patterns. While polydactyly can be a unique and interesting feature, it’s essential to understand its genetic basis and potential implications for cat health.
Can polydactyly cause health problems in cats?
In most cases, polydactyly is a harmless condition that doesn’t cause any health problems for cats. However, in some instances, the extra toes can lead to complications, such as arthritis, infections, or injuries. For example, if the extra toes are not properly aligned or are too long, they can put pressure on the surrounding tissues, leading to pain and discomfort. Additionally, polydactyl cats may be more prone to ingrown toenails or other toe-related issues.
Despite these potential risks, most polydactyl cats lead normal, healthy lives. Responsible breeders and owners can help minimize the risks associated with polydactyly by providing proper care and attention to their cat’s toes. This includes regular nail trimming, checking for signs of infection or injury, and providing a safe and comfortable environment for the cat to live and play. With proper care and attention, polydactyl cats can thrive and enjoy a high quality of life, regardless of their extra toes.
How is polydactyly diagnosed in cats?
Diagnosing polydactyly in cats is relatively straightforward, as it’s a visible physical characteristic. Veterinarians can easily identify extra toes during a routine examination, often at birth or during the kitten’s first few months of life. In some cases, radiographs (x-rays) or other imaging tests may be necessary to confirm the presence of extra toes or to rule out other potential causes of toe abnormalities.
A diagnosis of polydactyly is usually made based on a combination of physical examination, medical history, and genetic testing. Breeders and owners may also be able to identify polydactyly based on their cat’s family history and genetic background. For example, if a cat’s parents or siblings have polydactyly, it’s more likely that the cat will also have the condition. Once polydactyly is diagnosed, veterinarians and owners can work together to provide proper care and management to ensure the cat’s overall health and well-being.
Can polydactyly be inherited, and if so, how is it passed down?
Yes, polydactyly can be inherited, and it’s usually passed down from parents to offspring through a dominant autosomal gene. This means that a single copy of the gene is enough to cause the condition, and a cat only needs to inherit one copy of the gene from either parent to express polydactyly. The genetics of polydactyly are complex, and multiple genes may be involved, but the basic principle is that the condition is inherited in an autosomal dominant pattern.
The inheritance of polydactyly has significant implications for breeding programs, as it can be used to predict the likelihood of offspring inheriting the condition. Responsible breeders can use genetic testing and pedigree analysis to identify cats that are likely to carry the polydactyly gene and make informed decisions about breeding. Additionally, owners who are interested in breeding their polydactyl cat should work with a veterinarian or genetic counselor to understand the risks and benefits associated with passing on the condition to offspring.
Are there any specific health risks associated with polydactyly in cats?
While polydactyly is generally a harmless condition, there are some specific health risks associated with it. For example, polydactyl cats may be more prone to toe injuries or infections, particularly if the extra toes are not properly aligned or are too long. Additionally, polydactyl cats may be more likely to develop arthritis or other joint problems, especially if the extra toes put pressure on the surrounding joints.
To minimize these risks, owners of polydactyl cats should take extra precautions to protect their cat’s toes and overall health. This includes providing regular nail trimming, checking for signs of infection or injury, and providing a safe and comfortable environment for the cat to live and play. Additionally, owners should work closely with their veterinarian to monitor their cat’s health and address any potential issues promptly. With proper care and attention, polydactyl cats can lead long, healthy lives despite the potential risks associated with their extra toes.
Can polydactyly be treated or corrected in cats?
In most cases, polydactyly is a cosmetic condition that doesn’t require treatment or correction. However, if the extra toes are causing health problems or discomfort, surgical removal may be necessary. This is usually the case if the extra toes are malformed, infected, or putting pressure on the surrounding tissues. The decision to surgically remove extra toes should be made on a case-by-case basis, taking into account the individual cat’s needs and circumstances.
Surgery to remove extra toes is typically a minor procedure that can be performed under general anesthesia. The goal of surgery is to remove the extra toes and improve the cat’s comfort and mobility. In some cases, surgery may also be necessary to correct other toe-related issues, such as ingrown toenails or toe abnormalities. After surgery, owners should provide their cat with plenty of rest, pain management, and follow-up care to ensure a smooth and successful recovery. With proper care and attention, cats can thrive after surgery and enjoy a high quality of life.
