Why do a cat's nails fall off? - briefly
A cat's nails may fall off naturally due to shedding of the outer nail sheath as part of their regular growth cycle, or it could indicate an underlying issue such as injury, infection, or nutritional deficiency.
Why do a cat's nails fall off? - in detail
A cat’s nails may fall off due to a variety of reasons, ranging from natural processes to underlying health issues. One common cause is the natural shedding of the outer layer of the nail, known as the sheath. Cats regularly scratch surfaces to remove the old, worn-out outer layer, revealing a sharper, healthier nail underneath. This process is entirely normal and helps maintain the health and functionality of their claws. However, if the nail falls off entirely, it could indicate an issue. Trauma or injury, such as catching the nail on a surface or excessive scratching, can lead to a nail becoming loose and eventually detaching. Infections, particularly bacterial or fungal, can weaken the nail bed, causing it to fall off. Conditions like onychomycosis, a fungal infection of the nail, can lead to brittleness and detachment. Nutritional deficiencies, especially a lack of essential vitamins and minerals like biotin or zinc, can also compromise nail health, making them more prone to falling off. Additionally, systemic diseases such as autoimmune disorders or hormonal imbalances may affect nail integrity. In some cases, tumors or growths near the nail bed can cause structural damage, leading to nail loss. If a cat’s nails fall off repeatedly or are accompanied by other symptoms like swelling, redness, or pain, it is crucial to consult a veterinarian to identify and address the underlying cause. Proper nail care, a balanced diet, and regular veterinary check-ups can help prevent such issues and ensure the cat’s overall well-being.
