Even the cutest of kitties can develop a problem behavior for one reason or another, but most of them can be corrected fairly easily with the right information. Even if your cat doesn't currently exhibit any of these behaviors, learning about them now will make it easier to spot them in the future and quickly correct them before they get out of control.
So your cat's nails have become quite friendly with your couch or chair? Provide him with some alternatives and your furniture should be safe again in no time!
This annoying habit forces many people to give their cats up for adoption, but it can be avoided.
