Why Does My Cat Chew Plastic Bags?

Questions that can come up when working with families that have cats in their households, are often about a cat’s predilection for chewing on odd items. While plastic bags may seem like a strange choice for cats; from a cat’s point of view, they are very attractive. However, chewing on these bags can be dangerous for your cat as they can suffocate or choke on bags and bag pieces.

What’s so great about chewing plastic bags?
Plastic bags that come from a grocery or other food store can carry the lingering scent and even taste of food, which makes chewing them a pleasant experience. Many bags are also coated in substances such as cornstarch, stearates (salts of stearate acid), or are made of animal by-products such as gelatin, which makes them attractive to cats. Cats can also enjoy the crinkly noises that a plastic bag makes.

Another reason that cats will chew bags can be related to their dental health. If you find your cat engaging in these activities, a trip to the veterinarian to make sure her teeth are in good order is important. You may also want to discuss with your veterinarian your cat’s diet, as chewing on odd objects can be a symptom of insufficiency in daily dietary needs. Finally, boredom can be a major factor in habits like these. You should adopt a plan combining management (to keep your cat safe) and enrichment (to engage your cat’s physical and mental needs).
