What causes cutaneous horn in cats?

Answered by James Kissner

Cutaneous horns in cats are a fascinating yet peculiar phenomenon. These horn-like growths on a cat’s paws can be attributed to an overproduction of keratin, a protein that is essential for the growth of hair and nails. While keratin is necessary for normal bodily functions, an excessive amount can lead to the formation of cutaneous horns.

The exact cause of this excessive keratin production is not fully understood. It may be influenced by various factors such as genetics, hormonal imbalances, or underlying health conditions. Some cats may have a genetic predisposition to developing cutaneous horns, while others may experience them as a result of hormonal fluctuations.

Cysts can also play a role in the development of cutaneous horns. Cysts are sac-like structures that can form under the skin and contain fluid or semi-solid material. In some cases, these cysts can become inflamed or infected, leading to the production of excess keratin. As a result, the keratin may accumulate and harden, forming a horn-like projection on the cat’s paw.

It is important to note that while cutaneous horns may appear alarming, they are usually benign and not necessarily a cause for immediate concern. However, it is always advisable to have any unusual growths or changes in your cat’s skin examined by a veterinarian. They can help determine the underlying cause and recommend appropriate treatment if necessary.

In some cases, the cutaneous horn may need to be removed if it causes discomfort or interferes with the cat’s normal activities. This may involve surgical removal or other procedures, depending on the size and location of the horn.

Cutaneous horns in cats are caused by an overproduction of keratin, often influenced by genetic factors or hormonal imbalances. Additionally, oozing cysts on the skin can contribute to the formation of these horn-like growths. While usually benign, it is important to have any unusual skin growths evaluated by a veterinarian to ensure the health and well-being of your feline companion.
