Trying to work out the behavior of cats can be challenging. Whether it’s knocking things off shelves, curling up in tiny boxes, or anything else, they can often leave us both amused and confused.
One behavior that often seems unexplainable is when they chew on plastic. Is this a harmless habit or does it point to deeper issues they may have? Read on as we’ll explain why do cats chew on plastic.
The Sensory Appeal of Plastic
One of the main reasons cats chew on plastic is because they find the texture and sound appealing. It becomes a bit of a toy to them and an extra thing to keep their minds busy. As long as they’re not eating it, there’s not a lot to be concerned about here.
Cats can also be attracted to plastic as it instinctively intrigues them. This can sometimes be because plastic bags are now made with cornstarch, animal by-products, or gelatin-based compounds. These can emit a subtle scent that cats can detect, even if we can’t.
The crinkly noise of a plastic bag can also mimic the sound of prey moving through dry leaves, this can stimulate their predatory instincts, prompting them to bite. Cats can use their mouths to explore their environment, and chewing can be their way of investigating something unfamiliar.
Compulsive Chewing and Pica
Pica is a term for the compulsive chewing of non-food items. Humans can do this too, but it can also affect cats. It’s more common in certain breeds such as Siamese and Oriental Shorthairs that are predisposed to compulsive behaviors.
It can be caused by a few different factors. If your cat has recently had environmental changes, it may be showing this behavior as a comfort response. Pica can also be caused by being weaned too early as a kitten.
A good way to see if it’s pica is to notice if they are chewing on anything else. They are also likely to gnaw on the likes of wool, fabric, cardboard, or string. Try and give them something else to chew. You can also remove targeted items or take steps to make them unappealing.
Dietary Deficiencies or Hunger
Another reason cats may chew on plastic is dietary deficiencies or hunger. If your cat isn’t getting enough of the nutrients it needs, it may chew on items to try and satisfy that deficiency. Double-check to see if the food you’re giving is right for them.
They may associate the smell or residue with a treat, especially if the bag was used to hold food. If their bowl is empty and they have no access to any other food, this may be the reason.
Dental Issues or Teething
Just as with many animals, cats can chew on things to relieve discomfort in their mouths. This can especially be true for kittens. They may seek various textures out to try and soothe their sore gums.
As well as kittens, adult cats may do this if they have dental problems. Potential issues include gum disease, tooth resorption, or plaque build-up. Related symptoms to look out for are drooling, pawing at their mouth, and bad breath. Make sure they follow the best dental habits.
Boredom and Lack of Stimulation
Cats need plenty of mental and physical stimulation. This includes having playtime, social interaction, and environmental enrichment. Without it, they act out in a number of ways and it can cause depression. However, they may also chew on plastic.
Here, chewing can become a form of entertainment if your cat is bored. They may start nibbling on an object just because it interests them and it is a way to pass the time. If you feel as though this may be the issue, make sure you’re finding ways to engage their natural instincts.
Stress and Anxiety
Cats can become stressed or anxious quite easily. They settle into their environments and should anything change, they won’t like it. Moving home is the most obvious example of this but it can also be more subtle such as loud noises or changes in their owner’s routine.
In these situations, chewing can serve as a coping mechanism. This is even more likely if there aren’t many outlets for their stress. This can be seen as similar to how a human may bite their nails or twirl their hair when nervous.
If you think your cat may be stressed, try and find the reason for it. If it is a change in environment, they may just need time to settle into their new routine. In the meantime, using calming products may help them.
Attraction to Static Electricity
Cats are highly sensitive to touch, and static electricity can build up on plastic. When they brush against plastic, it can cause a static charge. This can lead plastic to cling to their bodies and can also give them a tingling sensation.
Given their notoriety for being curious, this can intrigue your cat, leading them to play and interact with the plastic even more. This is more likely to happen in dry environments with little humidity, such as heated homes in the winter.
The Risks of Plastic Chewing
A cat chewing on plastic can be seen as funny or cute, but there are some potential dangers to it. One is a choking hazard as a piece of plastic can break off and become lodged in their throat. If they do swallow it, then it can lead to internal blockages.
Some plastics will also contain dyes or chemicals that may be toxic to your cat if ingested. Finally, there is also a suffocation risk should they get stuck. Most of the time it will be harmless but letting them play with it isn’t a risk worth taking.
How to Stop Your Cat from Chewing Plastic
The best way to keep them safe is to keep all plastic out of reach. Make sure any store bags or wrappers are kept away in cupboards or containers. If that’s not possible, using a deterrent like a bitter apple spray can stop them from chewing.
Chew toys can be a safe alternative, or dental sticks if they are having teeth issues. Increasing stimulation is another effective way of distracting them from any plastic. Finally, if you are worried about your cat, make sure to take them to the vet.
