Why are a cat's nails falling out? - briefly
A cat's nails may fall out due to natural shedding of the outer nail sheath or underlying health issues such as infections, trauma, or nutritional deficiencies.
Why are a cat's nails falling out? - in detail
A cat’s nails may fall out 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 sheath. Cats regularly scratch surfaces to remove the old, worn-out outer layer of their claws, allowing new, sharper claws to emerge. This process is entirely normal and does not indicate any health problems. However, if the nails are falling out excessively or accompanied by other symptoms, it could signal an underlying issue. Fungal or bacterial infections can weaken the nail bed, causing the claws to become brittle and fall off. Conditions like onychomycosis, a fungal infection, or pyoderma, a bacterial infection, can lead to such complications. Nutritional deficiencies, particularly a lack of essential vitamins and minerals like biotin, zinc, or omega-3 fatty acids, can also affect nail health, making them prone to breaking or falling out. Trauma or injury to the paw or nail bed, such as getting caught in fabric or being torn during vigorous scratching, can result in nail loss. Additionally, systemic diseases like autoimmune disorders, where the immune system attacks healthy tissue, can cause nail abnormalities and shedding. For example, pemphigus, an autoimmune condition, can lead to blistering and nail loss. Parasites, such as ringworm, though primarily a fungal infection, can also affect the claws, causing them to deteriorate. Hormonal imbalances, particularly thyroid disorders, may contribute to poor nail health and shedding. Age-related changes can also play a part, as older cats may experience slower nail growth and increased brittleness. If a cat’s nails are falling out frequently or without an obvious cause, it is essential to consult a veterinarian for a thorough examination. Diagnostic tests, such as skin scrapings, blood work, or fungal cultures, may be necessary to identify the root cause. Treatment will depend on the underlying issue and may include antifungal or antibacterial medications, dietary adjustments, or management of systemic conditions. Regular grooming and monitoring of a cat’s nails can help prevent complications and ensure overall paw health.
