Cat chewing on plastic.

You might not ever expect to see your cat chewing on plastic bags, but as a veterinarian, I can report that it is not uncommon for owners to tell me that their cats eat plastic.

Quick Overview


Some curious cats can find the texture, smell, and taste of plastic appealing.


It's important to rule out nutritional, medical, and behavioral causes of a cat eating non-food objects like plastic (called pica).


if your cat eats plastic, keep these items out of reach and provide your cat with plenty of acceptable playthings.

The reasons behind this odd behavior are varied and may include natural curiosity of cats for new textures and tastes, or a medical condition such as anemia or hyperthyroidism leading your cat’s interest in plastic items. Eating non-food items such as plastic grocery bags can be bad news for cat health, so it is best to prevent this habit.

Are you wondering, “Why does my cat eat plastic?” Read on to discover the causes of plastic eating, and how to prevent it from happening in the first place.

1. Curiosity

Cats are known for their inquisitive natures and are often attracted to new sensory experiences. Plastic items such as shopping bags have a unique crinkly texture which can be fascinating for cats, especially young, playful kittens. The way plastic items move when played with can also stimulate cats’ predatory instincts, and you may see them pouncing and biting at them as if they were a small mouse or bird.

2. Scent and Taste

Your cat may chew plastic out of genuine confusion as to whether it is cat food! Plastic bags are often coated in corn starch and stearates, and can be made from gelatin. Cats have an excellent sense of smell and might find the scent of the starch and gelatin appealing, and think that the plastic is worth having a chew on to see if the taste matches the odor.

3. Anxiety

Cat behavior can be complex, and cats who are anxious or stressed can present in unusual ways. Some cats will hide away, change their interactions with owners, become aggressive, or urinate in odd places. Others might develop symptoms of an obsessive-compulsive disorder, which can include repetitive and continuous chewing of non-food objects such as plastic grocery bags.

4. Pica

Some cat breeds have a known genetic predisposition to eating non-food items.

The condition of eating non-food items (pica) is a complicated disorder that has multiple potential causes. It can be a serious and debilitating problem, causing severe danger to cat health. Eating plastic is a fairly common presentation of pica, and can be linked to three main causes.

Breed: Some cat breeds have a known genetic predisposition to pica. Burmese and Siamese cats both appear to be prone to ingesting non-food objects, so precautions should be taken if with these breeds as to what objects are accessible to them. The condition can start from a young age.

Poor diet: If your cat’s diet is not providing all the nutrients your cat needs to thrive, this might induce pica as your cat tries to source essential nutrition from objects other than their cat food. Cats should be fed a good quality, balanced and complete cat food to prevent a nutritional health issue.

If their diet is restricted for any reason, your cat might need supplements, but this should always be discussed with a veterinarian or qualified feline nutritionist.

Medical condition: Certain health problems in cats can trigger pica, which can then lead to your cat ingesting various unsuitable things, including plastic items. Known health issues causing pica include dental disease, anemia, hyperthyroidism, and brain tumors.

It would be unusual, but not impossible, for cats with these medical conditions to have eating plastic as the sole symptom. Always monitor your cat for signs of ill health such as a change in appetite, urine, or poop, changes to their behavior and sleeping pattern, or other signs of illness.

Why Is Eating Plastic Bad?

What’s the harm in your cat having a nibble of a shopping bag or two? Well, actually, quite a lot! Plastic items can’t be digested by cats, so if they eat a certain amount of it, they might end up with an intestinal blockage. This can be a serious concern, causing lethargy, vomiting, and diarrhea and potentially needing major surgery to correct.

Plastic bags are also a suffocation risk, especially for young kittens who might be able to get right inside them and become trapped. Shopping bags with handles can also get caught around cats’ necks, risking neck injuries or strangulation.

How To Prevent Plastic Eating in Cats

The good news is that there are some simple modifications that cat owners can make to their cat’s environment to reduce this worrying behavior.

1. Prevention Is Better Than Cure

It is always a safe idea to keep plastic out of reach of cats and kittens. Store grocery bags out of sight, and never use them as a play object with your pet. It is obviously difficult to keep all plastic items away from pets, but being vigilant about loose objects such as bags is a good habit to get into.

2. Safe Chew Toys

Some cats just love to chew, for stress relief, as a boredom buster, or just for fun. Providing objects that are safe for your cat to chew on will fulfill this need, and hopefully, stop them from turning to unsuitable objects such as grocery bags. If your cat doesn’t seem interested in a cat chew, try rubbing some catnip on it to encourage interest. If you own an indoor cat, providing some cat grass can be great for safe chewing.

3. Enrichment

Puzzle toys keep cats stimulated and entertained so they don’t look for plastic to chew.

Boredom and frustration can lead to undesirable behaviors in cats. Providing lots of stimulation and playtime is key for cat owners to live a peaceful life. Puzzle feeders, cat toys, cat trees, and scratching posts are all excellent for cats, but even a cardboard box will provide entertainment!

4. Bitter Sprays

If there are plastic items that your cat seems irresistibly attracted to chewing, and you can’t put them out of reach, consider coating it in a cat-safe spray. Bitter sprays deter cats from chewing on objects in a safe way and are useful if separation is impossible.

5. Professional Help

If your cat is displaying symptoms of pica, it is recommended to seek advice from a veterinarian, who can examine your cat and run any necessary tests to rule out medical causes. If your cat is deemed healthy, then a qualified feline behaviorist will be able to assess for anxiety or stress.

Frequently trying to eat plastic is a problem for cats that should be addressed.

A curious cat having a play and a little experimental chew on a piece of plastic is fairly normal for these inquisitive pets, but eating plastic in any kind of quantity is bad news for feline health. Eating unusual things (pica) can be predisposed in some breeds, but can also be caused by nutritional deficiencies, anxiety, and certain medical complaints.

If your cat eats plastic, seek advice from a veterinarian and provide them with plenty of cat-safe alternatives to chew as well as lots of enrichment to keep them happy and healthy in mind and body.
