When cats chew on inanimate objects, such as electrical cords, the behavior may be caused by an obsessive-compulsive disorder (OCD), or other environmental or health-related factors. For example, it could be a dental issue, a way for the cat to relieve stress, or just a case of mistaken identity.

Whatever the reason behind it, it's dangerous for cats to chew on electrical cords, not to mention that this activity can destroy your electrical appliances or at least force you to replace the cords. Fortunately for you and your cat, there are a number of ways you can address this behavior.

Reasons for Chewing

There's some mystery surrounding why cats choose electrical cords to chew on. One theory is that the cord resembles another animal's tail and that basic feline instinct compels the cat to attack anything that looks like a tail—although this reasoning doesn't address why the cat would continue to chew the cord once it discovers there's no animal attached. Additional reasons for cord chewing may include:

Obsessive-Compulsive Disorder

Obsessive-compulsive disorders (OCD) that involve chewing and gnawing behavior most often develop in Oriental-heritage cats, such as Siamese, Burmese, Oriental Shorthair. These felines may develop a strong urge to chew, suck, and sometimes even eat inedible objects.

Although cord chewing may be the primary OCD behavior you observe in your cat, you may spot other symptoms as well. There doesn't seem to be an explanation for why some cats develop a particular combination of OCD symptoms.

  • Self-mutilation, particularly involving the tail, and repetitive tail chasing are among the first symptoms of OCD.
  • Overgrooming, characterized by a cat licking and chewing its fur so vigorously that it starts to fall out in spots, is also common.
  • Obsessively sucking, licking or chewing on fabric, a condition referred to as wool sucking. This behavior isn’t completely understood, and multiple causes have been suggested, including premature removal of the cat from its mother. If your cat has Siamese-like tendencies, the chewing may be influenced by genetics.
  • Feline hyperesthesia may also afflict cats that suffer from OCD. A cat with this disorder may exhibit symptoms such as rippling of the skin and self-mutilation behavior.

Dental Issues

Cats that have pain in their mouths caused by dental problems may indulge in gnawing behavior in an attempt to relieve the discomfort. Up to 70% of cats develop periodontal disease by the time they turn 3 years old, so it's important to address this proactively with regular veterinary dental care, including checkups and cleanings.

Boredom or Inactivity

If your cat is older, it may have a combination of issues that prompt chewing behavior. As they age, nearly all cats develop some degree of arthritis, which can result in a drastic reduction in their activity level. When a cat isn’t able to move around and exercise, explore, or interact as much with the world, boredom and the resulting stress may cause it to seek other outlets.

Medical Issues

At an older age, there may also be metabolic issues, such as hyperthyroidism, that raise a cat's activity level and increase its urge to gnaw. A blood screening panel may reveal a treatable issue that resolves the chewing behavior.

In rare instances, a nutritional deficiency called pica is associated with eating odd materials. It's speculated that the cat instinctively understands that a nutrient is missing from its diet and seeks to replace it, but may choose inappropriate items to ingest. Some cats that suddenly begin targeting inedible objects are found to be anemic.


Stress can prompt a wide range of odd behaviors. In these cases, the chewing serves to relieve anxiety and simply makes the cat feel better emotionally.

How to Stop Chewing

Take your cat to the veterinarian for a checkup if it displays inappropriate chewing behavior so that any underlying health problems can be discovered and addressed. In the meantime, take steps to keep your cat safe.

  • Cover electrical cords by running them through PVC pipes. You can also make them less appetizing by painting them with hot sauce or a commercial bitter apple substance.
  • Smear the cords with a menthol-containing substance, like Vicks VapoRub, to keep your cat at bay since the smell can be quite off-putting. The Ssscat motion detector, which “hisses” if the kitty comes close, can also be a humane kitty deterrent.
  • Offer the cat alternatives to chew, such as cardboard. Some cats also enjoy gnawing on the smallest-size canine rawhide chews—dip them in warm water and zap them in the microwave first to soften them a bit.
  • Add digestible fiber to your cat's diet, which prompts some cats to reduce their chewing activity or even stop altogether. Fresh cat greens, green beans, or lettuce added to the cat’s food bowl may do the trick. Some of the “hairball formula” commercial diets may also work, as they provide increased fiber as well.
  • Reduce anxiety to help eliminate the need for chewing. Consider trying a synthetic kitty facial pheromone to relieve stress and soothe your cat. Otherwise, make sure your cat's litter box is spotless and that it has enough toys and playtime with you to stave off boredom.
