Yes, cats need their nails trimmed regularly to keep them from becoming too long and sharp. Trimming your cat's nails can also help prevent scratches on furniture and carpets. Most cats are not comfortable with having their nails trimmed, but with patience and positive reinforcement, it can become a regular part of your cat's grooming routine. It is important to use a nail clipper specifically designed for cats, as human nail clippers can be too harsh for their delicate nails.
