How to Stop a Cat From Chewing Everything

Restrict your cat’s access to things she loves to chew. For example, power cords are dangly and fun when viewed by a cat. Tape them together and to the wall to remove some of the attraction.

Smear target objects with tastes that are unpleasant to cats. You can try toothpaste or mint or lemon juice, or anything else that makes your cat turn and run. You may have to experiment, as cats are like people in that they have different tastes. Also, bear in mind that these objects will smell like toothpaste to you, too.

Consider if the problem is a medical one. If your cat keeps chewing its own body or tail, perhaps there are mites or an excessive number of fleas present. In this instance, the cat is trying to alleviate the itching, not hurt itself. There are creams and medication available to fix the medical problem.

Provide toys the cat is allowed to chew and train it to reach for its toys whenever it needs a good chew. Some breeds even need to consume inedible materials such as wool in order to streamline digestion of their food. It's possible to convince a cat that it owns something, so you could wean the cat off of chewing your sweaters and onto chewing its very own piece of wool.

Remove the cat’s premolars and molars. Obviously, this is not a job for you but for the vet. You should consult a veterinarian to see if this is a good option for your cat. While it’s a bit extreme, it does prevent the cat from attacking objects that could cause harm while still allowing it to eat.
