It takes about a week for a cat's nail to grow back from the root, but it will only grow a little. It may take about a month to fully grow out. During this period, owners can supplement their cats with more vitamins and calcium to make their nails healthier and help their nails grow.

Reasons for broken cat nails

1. The cat’s nails are too long. During the cat’s daily activities, it is easy to hook things. Under the influence, the nails will be torn off.

2. Cats’ long-term lack of vitamins and calcium leads to underdeveloped nails. The nails are very fragile and easy to break.

3. When the owner cuts the cat’s nails improperly, or does not use cat-specific nail clippers, the cat’s nails will break.
