Why Does My Cat Chew on Cardboard?

Owning a cat presents an opportunity to have a cheerful and contented playmate. Then again, as your furry family member grows up, it’s possible you’ll get worried when you notice your cat chew on cardboard boxes.

 There are a few reasons why your furry friend might adopt this behavior.  Whatever the reason, you should stay close and keep an eye on your cat and look for any noticeable changes that may help determine the new behavior’s cause. 

Even though it is not uncommon for a cat to do this, chewing on cardboard and packing containers is often associated with pica in some cats. Pica is defined as “the persistent chewing and consumption of non-nutritional substances that provide no physical benefit to the animal”.

 According to the University of California Davis Veterinary School, “It can be a symptom of an underlying medical problem, such as nutritional deficiencies, or behavior problems, such as anxiety, boredom, or true compulsive behavior”.

 Due to this fact, you might want to seek the advice of a veterinarian in case your cat has pica-related signs. Besides that, your cat could also be chewing on cardboard for various other reasons, including:

1. Boredom

This kicks when the cat is bored with old toys and has lost interest in the other people or animals around them. Undoubtedly, cats find enjoyment in playing with different items from the human world as they are something new, including cardboard! The texture and sounds made of the cardboard may be a distraction from boredom and amusing for your feline.

2. Helps With Itchy Gums

At some point of teething, the cat’s gums become itchy. If your cat is teething, they may use the cardboard to give their gums a scratch by chewing on almost anything they can find they think may help.

In most cases, your cat will choose cardboard as they find it comfortable and easy to chew. But even if teething, studies show that dental diseases have become common for many cats above four years of age.

Your adorable feline could also be suffering from sore gums, tartar, gingivitis, and plaque. These are serious dental conditions that may impact your cat’s feeding, and because of this, their well-being.

Chewing on objects similar to cardboard may relieve the itchiness on sore gums, but it is no substitute for appropriate dental care. Make sure that your cat has regular dental checkups and check out our article on Cat Dental Care.

Animals communicate through movements. Tearing into paper and cardboard may be your cat’s way of saying ‘I don’t like the food’ or ‘I am hungry. Figuring out the correct sort and amount of food that your cat needs is very important, and it could be a mitigation measure for cardboard and paper chewing. In case your cat ingests the cardboard instead of only playing and having fun, you may wish to try a different type of cat food to see if that helps.

Some steps that may assist with correct eating include feeding the cat on time, frequent nutrition changes, and giving the cat the appropriate quantity.

Cats are pleasant pets and they can cohabit harmoniously with people and other pets. Unlike dogs that pee on an area to announce dominion, cats use their enzyme to do the same. Cats are not known to be territorial.

On the other hand, chewing on cardboard leaves the cat’s enzyme on it. This can be a means of telling other cats that the object/toy belongs to them.
