Most cat owners realize that oftentimes their cat is scratching objects because they are trying to sharpen or trim their claws, however, there are other reasons for feline furniture scratching, as well. Scratching can be used as a source of communications. You see, cats have scent glands on their paws, so by scratching the corner of the couch, they’re claiming that spot. If you have multiple cats, you may see the same spot claimed by multiple cats, and around it goes. For whatever reason, it has gotten into cat owners’ heads that any problem behavior can be fixed by spaying or neutering, which is not the case when it comes to scratching (although, you really should get your cats fixed for several other reasons).
