Aside from destroying your personal items, your cat may endanger itself by chewing unsafe items, such as electrical cords. But, why do cats chew on wires? Let’s find out why and how you can prevent such behavior.

Why Do Cats Chew On Cords? 

If you are worrying because your cat chews cords at home, you’re not alone. This is a common concern many cat owners need to deal with at home every day. There could be many reasons why cats chew on cords. It can range from simple teething issues to more serious underlying medical conditions such as Obsessive Compulsive Disorder (OCD). 

Cats explore their environment using their mouth. So, it’s not a surprise that they may chew on different items at home. This habit may give them a soothing feeling, entertainment, or satisfaction. Electrical wires can be a perfect target because of their size and structure. Their easy to reach and gnaw on, plus, they are found in many places at home. They also resemble tails that may stimulate the cat to “catch” and bite. 

To fully understand why cats keep chewing on cords, let’s discuss the possible reasons for this bothersome habit. 

Boredom or Lack of Activity

Cats are instinctively curious creatures, so it’s natural for them to roam around and actively explore. Since they are independent animals, it’s easy to assume that they are good at being alone in the house. But, without proper physical and mental activities, cats can get bored too. Once the boredom kicks in, they’ll start to find entertainment by developing destructive behaviors such as chewing. 

Being alone at home is not the only cause for boredom in cats. As they age, their activity levels may plummet due to certain medical conditions or joint problems. These may limit them from enjoying the activities they used to do and develop boredom.  

Dental Issues

Chewing may give a soothing feeling to your cat’s gums. So, cats suffering from dental issues tend to resort to this bothersome habit to get some relief. Problems in the gums and teeth are common in adult cats. In fact, a study by Cornell Feline Health Center reveals that 50-90% of cats older than four develop various dental issues. So, if your cat keeps chewing cords, it may be time to get a dental check-up to rule out this cause.

Adult cats aren’t the only ones seeking dental comfort from chewing. You may have noticed your kitten chewing on cords or other items at home, too. Kittens lose their baby teeth around 3 to 4 months of age. During the process, they’ll feel some discomfort from sore gums. That is why they resort to chewing to soothe the pain they feel.

Medical Issues

The increase or decrease in physical activities may be influenced by certain medical conditions. As previously mentioned, joint problems, such as osteoarthritis, may limit a cat’s mobility. Thus, forcing the cat to turn to other activities instead, like chewing. On the other hand, hyperactivity may also be brought about by illnesses, such as hyperthyroidism. This spike in energy may cause your cat to be abnormally active and increase its urge to chew more including electrical wires. 

As soon as your cat’s thyroid levels are stabilized, its activity level will reduce back to normal. So, if this is the cause of the chewing habit, then it’s treatable.  


Obsessive Compulsive Disorder is a behavioral issue that can develop in cats, too. OCD is more common in Siamese and Burmese cats. This disease causes the cat to overly exaggerate the otherwise normal actions in felines, such as grooming. Cats with OCD also tend to chase their tails and even end up self-mutilating. OCD also causes affected felines to chew, suck, and eat inedible items such as fabrics or wool. 

This obsessive chewing may also be applied to other items at home such as electrical wires. If you’ve observed your cat chewing cords along with other symptoms mentioned, it may be suffering from OCD. 


Felines eating inedible objects at home may be suffering from pica. A mild case of pica may cause the cat to suck or lick the object. But those with severe cases may consume the entire item. This poses a risk of intestinal blockage or in the case of electrical wires, electrocution in cats. There isn’t any known cause for pica, although there are speculations that it may be due to nutritional deficiencies, genetics, or other medical issues. 

The treatment for pica varies depending on the underlying cause or other existing medical or behavioral issues of the cat. Full recovery may happen. Additionally, continuous management could also be another solution in certain cases. 


There are numerous causes of stress in cats. Depending on your cat’s sensitivity, a mere change in the litterbox or the position of certain pieces of furniture may stress out cats. Having unusual events at home such as the arrival of visitors, children, or other pets may also cause stress. Other more serious causes include boredom, physical pain, lack of basic needs or activities, and lack of socialization. 

Stress can induce abnormal eating habits including destructive chewing in cats. To relieve stress, cats may start biting your personal items, including electrical wires or cords.
