Some cats enjoy climbing into empty cardboard boxes or cat carriers, especially if food treats have been left inside. Ping pong balls and walnuts make inexpensive toys that many cats love. Cats may even find some dog chews appealing. Indoor cats with little access to grass or other vegetable matter may chew houseplants. Offer them lettuce, catnip, or their own kitty herb garden in exchange.
Some cats are more likely to suck or chew on material such as rugs or clothing.
PPP Preventing Problems To keep your cat away from problem areas, first try child locks, barricades or closed doors. If you can remain out of sight and use remote punishment, your cat should learn without fearing you. Use a water pistol or loud noise to stop the behavior. Destructive chewing can be discouraged by using commercial anti-chew sprays, mentholated products, vinegar, or a little cayenne pepper mixed with water. You should not punish your cat unless you have provided your cat with an alternate scratching area for it and have rewarded it for scratching there.
