It is normal for cats to lose nail flakes. Cat’s nails play important roles such as burying feces, grabbing objects, and climbing up and down. If the cat exerts improper force, it will cause nail flakes to fall off. It is important that the nails are not red and swollen. The owner does not need to worry about the status. If redness and swelling occur, the owner should apply anti-inflammatory drugs and it will recover after a period of time.
