Cat nails can heal themselves if they fall off. Generally, cats will replace their nails regularly. This is normal. If a cat's nails are broken due to trauma, they can grow back. However, owners should disinfect broken nails in time to avoid wound infection. Severe infection may lead to large-scale ulcers on the cat's feet.

Causes of cat nails falling off

1. Cats replace their nails normally. Cat's nails are actually made up of layers, and every once in a while, the outer layer of the cat's nails will fall off.

2. Cat’s nails are too long. During the cat’s daily activities, running and jumping, it is easy to hang on the sheets or get stuck in the gaps, causing the nails to break.

3. Cats lack vitamins for a long time or lack water in their bodies. The cat's cuticles will become very dry and the nails will break easily.
