Keep your cat's nails well trimmed. You or your parents can learn how to do this yourselves. You must use a sharp pair of nail trimmers made specifically for cats (don't use human trimmers). Ask your veterinarian to teach you how and to recommend some good nail clippers.
Many people consider declawing surgery. Many veterinarians believe declawing is a painful and unnecessary surgery and refuse to do it for humane reasons. Instead, they advocate training your cat to use a scratching post. However, some veterinarians still believe declawing is a safe procedure.
This surgery removes the claw, the nail bed and often part or all of the last finger. If an animal is declawed, you have to take care that he doesn't ever get outside because he will not be able to protect himself. He won't be able to climb as well, either.
