Since adopting our youngest cat, Kalista, no cardboard box that enters our apartment is safe.
For example, we’ve had a box of floorboards in our living room since we moved in and Kalista has chipped at the box slowly finally exposing what the planks look like. I swear, if we didn’t open our packages immediately, she would open them for us like a kid on Christmas morning.
While it can be frustrating coming home to a ripped up box or waking up to little pieces of cardboard scattered across the apartment, chewing and ripping cardboard is actually a fairly common habit for cats to have.
That being said, let’s dive into the reasons why your cat may have this destructive behaviour and what it means!
I’M HUNGRY!!
Some cats like our youngest, Kalista, are picky eaters and will refuse to eat if they aren’t given the food that they want or the exact batch or consistency that they are used to. Kalista is one of those weird cats who will start chewing on cardboard anytime she is hungry but doesn’t want to eat the food that we give her.
Truthfully, this is one of the most annoying behavioural traits Kalista has since we know she’s hungry and we are trying to give her food, but she won’t accept it. That also said it comes in very handy because it gives us a clue of whether or not Kalista has eaten enough from her previous meal, as she’s a cat who likes to walk away from her meals even if she is still hungry. We assume this is both tied to her pickiness as well as her extreme curiosity.
MY GUMS ARE REALLY SORE
Many cats begin developing dental problems by the age of 3, including issues like gingivitis. Cats may choose to chew on soft objects such as cardboard as a way to soothe their gums from the pain and inflammation caused by these dental issues.
Dental problems can be avoided by ensuring that your cat has the proper toys to chew on, their teeth are regularly brushed and they get regular cleanings/dental checkups by the vet.
Dental problems are more common for cats who are on an all wet food diet, though it is also a myth that kibble cleans a cat’s teeth. Kibble, in fact, can help reduce tartar and plaque if they are fed kibble that is large enough in size. This is the thought behind dental treats such as greenies, however, it’s important to ensure that your cat is actually chewing on these large pieces of kibble/dental treats rather than inhaling them as many cats do.
If your cat is younger your cat may be teething and may not be experiencing any dental disease, though they will still be experiencing very sore gums.
Similar to dental disease, dental toys will be an asset, especially ones you can put into the freezer. My favourite is the Petstages Dental Chew Wheel since it has little nubs around it to massage out your cat’s gums.
I’M BORED AND I DON’T HAVE ENOUGH TOYS!!!
It’s in a cat’s primal instincts to rip apart and play with their prey, so it’s for that reason that many vets believe that cats tear up cardboard boxes.
Cats may choose to shred cardboard boxes with their nails or teeth as a form of relaxation and play when they have a lot of energy.
If you have a cat like this you may want to look into getting cardboard cat scratchers or even into scratchers such as the Kong Wrangler. If you continue to allow your cat to chew and rip up cardboard boxes (which isn’t an issue) make sure to monitor them to ensure that they are not digesting any of the cardboard as it may cause an obstruction.
Boredom chewing can also be a sign that your cat has Pica, however, Pica usually also includes chewing on garbage, plastics and other objects. If your cat is tearing up more than just cardboard I would definitely recommend reading my piece about how we got our eldest cat, Beau, to stop chewing on absolutely everything!
Pica can also be a sign that your cat has nutritional deficiencies or was weaned too early, so it is best to get your cat checked out before anything bad comes of it.
I’M TRYING TO MAKE THIS BOX COMFIER
Does your cat like sitting in boxes? Do you find yourself building custom homes for them? Well, take note of where they are chewing their cardboard box.
If it seems that your cat is chewing or ripping the same pattern into the cardboard box you may actually have a designer on your hands who is actually trying to manifest their vision of comfort.
Although rare, some cats have been known to chew holes for their heads, chins, or other limbs to fit comfortably in their cardboard boxes. Some cats have even been known to carve out little peepholes so they can make sure that they are completely safe while in their cardboard castles.
This is actually one of the least common reasons why cats chew on cardboard boxes, so consider yourself a very lucky pet parent if you have one of these special kitties.
THIS IS MY BOX, DON’T TOUCH!
Similar to behaviours like kneading or bunting/headbutting, cats may chew on cardboard boxes as a form of marking their territory.
Since cats feel safer when things smell like them it can be safely assumed that chewing on objects is another form of marking their territory as it both physically shows their territory as well as scents the location.
Cats who are insecure or more commonly scared may tear up cardboard boxes more frequently than independent cats.
It is important to make sure that your cat is not suffering from anxiety or stress as those tend to snowball into other behavioural issues such as ripping out their own hair and can sometimes even cause illnesses or ailments to progress faster.
If you think your cat is experiencing anxiety or stress I recommend talking to your vet about steps you can take to help reduce the stress.
For us, we’ve scheduled our cat’s feedings as well as playtimes, we play them calming music when they show signs of being strung out and we’ve given them feeder toys to keep them busy and stimulate their minds while eating.
Some vets will recommend a product called Feliway which releases a pheromone meant to replicate a mother cat’s scent. This has proven to help calm down many cats, however, it is important to know that it does not work for all cats.
Unfortunately, Beau is a cat who was not affected by Feliway though we’ve had many friends who have solved behavioural issues with it. Again, speak to your vet about this product to see if it may be a good fit for your household.

YOU’VE UPSET ME / YOU’RE IGNORING ME
Every so often we’re not the best pet parents we can be and we get our little ones angry or upset at us. So what do our cats do? Well, sometimes cats will take out their anger on cardboard boxes, our couches or sometimes even our skin.
Similar to anxiety and stress it’s important to make sure that we are aware of what the caused of the anger or upset is to ensure we do not repeat our behaviour in hopes of appeasing our cats.
At the end of the day, it’s important to remember that we live our cat’s houses and not the other way around ;).
A number of times destructive behaviours are linked to owners not paying attention to attention-seeking cats. Now, that’s not to say that you should begin paying attention to your cat and rewarding them for their destructive behaviour, as that will cause more issues, it does, however, mean that you should make sure that you are playing with your cat regularly.
If your cat needs too much attention or is young, consider getting them a playmate. Now, that being said, getting your cat a playmate is not going to solve all behavioural issues, however, it will make sure that your cat has a partner to help burn off some of that extra energy they have built up inside of them.
HOW DO I STOP MY CAT FROM CHEWING CARDBOARD
When deterring a cat from a specific behaviour it is important that you do not scold your cat by yelling or hitting them. You may, however, be interested in getting yourself a deterrent spray or compressed air that makes a hissing sound. I would recommend against blow horns or other loud deterrents as they can traumatize a cat.
Alternatively, you can also train your cat with a clicker or by snapping your fingers close to them. You can also begin teaching your cat specific commands like “uh-uh” or “tsk” although you’re going to want to make sure that their deterrent word isn’t a word you commonly use or their name.
I personally prefer sounds to words just so I can make sure that I’m not freaking out my cat by mistake by using a similar sounding word to their “deterrent word.”
CONCLUSION
Though chewing and ripping up cardboard boxes is often harmless, it is a form of destruction you’re going to want to keep your eye out on. This is especially true for cats over the age of 3 who may be dealing with dental diseases.
In general, it’s a good idea to keep track or keep a log of your cat’s behaviours to see if there are any patterns and if ever you have any further questions to approach your vet with them.
So, pet parents, I’m curious how many of your cats chew on cardboard? What did the reason end up being? Let me know in the comments below!
My new kitten Harley, he is 8 weeks old and so layful has me home 24/7 and has an abundance of toys and lots of play time. When I got him he was so tiny not drinking, was really worried he would not make it, I took him to the vet and they said he was 4 weeks old when I got him,we put him on formula and he literally went full speed to where he is now, I had no idea he was so young as I got told he was the runt of the litter,but he has a tendency for biting, and he attacks cardboard boxes very aggressively any suggestions, Thanks in advance
Hello!
It’s nice to know that I am not alone here! I have had 3 cars in my lifetime and 2 of the 3 were “chewers!” My first cat chewed the corners off of plastic grocery bags. I have now discovered through your post that he did that because he was weaned to early. To be honest he was a pretty crazy cat. Very high strung! Lol while having some service done by the cable company, I got to chatting with the “Cable Guy” and he had told me the same thing. I had no idea. He was born to a stray that used to hang around a friend’s house. And we were afraid that weren’t going to make it if left in that situation. One of his siblings got into something that she shouldn’t have and found dead by the shed. So I took him home and bottle fed him. Now I live in my cat Coals (8 years old) house! And he chews on plastic and boxes. I believe that he does it out of spite stemmed from boredom. When he wants MY attention (he doesn’t do this to my boyfriend) he chews. When I am in bed sleeping and he wants me to get up, he will start chewing on something next to the bed to wake me. If I don’t get up….he will go across the room and chew and won’t stop until my feet hit the floor! If I have gotten out of bed,(restroom) and I start walking back to the bed he will attack the back of my leg (claws and teeth). It’s unbelievable! He doesn’t eat any of it…just chews. I am pretty certain he uses it as a forum of communication because if I walk past his litter box and it is not up to specs he will attack my legs as well. Basically when something isn’t right or the way he wants it he will get ahold of my legs. Then I have to walk around and try to figure out what’s “got him going”, empty food bowls? Dirty litter? Not getting the attention he requires lol. While at times helpful it is rather quite irritating because I usually end up bleeding!! (nothing serious but painful just the same.)
Thank You for sharing this information.
I’ve had Mirmo for 2 weeks now. I adopted him and he is 1 1/2 years old. He started shredding a cardboard box 4 days ago. It’s a new one I put down for him on the floor. Big enough for him to sleep in but still cozy enough so he doesn’t have much extra room to sprawl in. Since reading your article I have noticed he is creating areas on one side, lengthwise, that gives him chin rests. He can now lay in the box but keep his head resting where he is able to see what is going on. He is not eating it as I watch him chew and spit. Does make a mess.
I feel you. We recently tried giving Kalista a new cardboard home and she destroyed it within days. Let’s just say… the house has an extra window… or two 😉
Our cat Jingles started doing this several months ago. She has always enjoyed inhabiting the empty Amazon boxes but never shredded them before. I really thought something was wrong with her. She does have dental issues and we take her in regularly. And she doesn’t seem to eat the cardboard. Just leaves little bits of it everywhere. It does seem that she qualifies for several reasons… she plays hide and seek with us when she wants attention, and she hides in her ‘home’,box (a small moving box). She will sometimes head to the box after I serve her meal – maybe I didn’t prepare the wet food to her liking? Sometimes I think she is just bored. I will mention it to the vet at our next visit. I was surprised to see how many people asking about this very thing popped up in my search.
We’ve definitely found Kalista has a few reasons to chew on cardboard. These days it’s mostly boredom or hunger. Since our cats are on an eating and playing schedule, it’s been a bit easier to deduce which it was for Kalista!
it bee a form oh art !!! 3 dee and all….grate job kalista 😉 ♥♥♥ we like de… tear strip ee fect…. ewe put inta play on de rite side 🙂
Kalista is always creating art. The most artistic kitty I know!
We’ve had Ellie for two years and just a few months ago, she started chewing a box. She’s never done that before – or since! I must admit it was entertaining – she took it so seriously. Her teeth are okay per the vet – so I’m going with the “you’re ignoring me” explanation. Now, the box is on the table next to where I work. It seems like when she thinks I’m ignoring her, she’ll start chewing the box. It’s always something! 😉
The things cats will do to get our attention… :’)
