What should I do if my cat’s nail splits into a thin layer?

You do not need to worry about a cat’s nail splitting into a thin layer. During growth, cats periodically shed their nails to keep them sharp, and a cat’s nail is layered, so the outer layer cracks a bit during shedding, which is normal. In addition, overly fast nail growth or dry weather can make nails crack more easily, so trim your cat’s nails regularly and use a humidifier in autumn and winter. Finally, vitamin deficiency can also cause nail cracking, so pay attention to a balanced daily diet and avoid feeding the cat a single food for long periods.
