Understanding Why Cats Chew on Plastic

Cats are curious creatures, and their love for chewing on plastic can stem from a variety of reasons. From playful instincts to health issues, here are the main causes, based on insights from trusted sources like Purina and The Spruce Pets.

1. Pica: Eating Non-Food Items

Pica is a condition where cats (and sometimes dogs or humans) feel compelled to eat non-food items like plastic, fabric, or paper. This behavior might be linked to nutritional deficiencies, such as a lack of vitamins or minerals, though the exact cause isn’t always clear. Certain breeds, like Siamese and Burmese, may be more prone to pica due to their curious and investigative nature. If your cat is obsessively chewing on plastic, pica could be the culprit, and a vet visit is a good idea to check for underlying issues.

2. Sensory Stimulation

Cats have sharp senses, and plastic offers a unique sensory experience. The crinkly sound of a plastic bag or the smooth, slightly resistant texture of a plastic bottle can be exciting for cats. According to Embrace Pet Insurance, this mimics the rustling of prey in grass or leaves, triggering a cat’s hunting instincts. The combination of sound and texture makes plastic an irresistible target for play and exploration.

3. Attraction to Food Scents

Plastic items, especially grocery bags or food containers, often carry lingering food smells that cats find tempting. Even after the food is gone, traces of meat, fish, or other treats can remain, drawing your cat to chew on the plastic. Hill’s Pet notes that some plastics are coated with substances like cornstarch or animal by-products, such as gelatin, which can smell like pet food to cats, making them even more appealing.

4. Teething in Kittens

For kittens, chewing on plastic is often a normal part of teething. Between 3.5 and 7 months of age, kittens lose their baby teeth and grow adult ones, which can cause discomfort. Chewing on hard objects like plastic can help relieve this pain. This behavior usually fades as they grow, but providing safe teething toys can prevent them from targeting plastic.

5. Boredom or Lack of Stimulation

Cats are natural hunters and need mental and physical stimulation to stay happy. If your cat is bored—especially indoor cats with limited access to varied environments—they might chew on plastic to entertain themselves. Pet Health Network explains that plastic’s interesting textures and sounds can become a source of fun for an under-stimulated cat. Adding more playtime or toys can help redirect this behavior.

6. Stress or Anxiety

Stressful situations, like moving to a new home, a new pet, or changes in your routine, can make cats anxious. Chewing on plastic can be a coping mechanism, similar to how humans might bite their nails when nervous. Purina US suggests that this behavior might be one of many signs your cat is feeling stressed, such as hiding or excessive grooming.

7. Dental Issues

Cats with dental problems, like gum disease or tooth pain, might chew on plastic to ease discomfort. The act of chewing can provide temporary relief, much like how a teething kitten behaves. Regular dental check-ups and at-home teeth brushing can help prevent this issue.

8. Underlying Medical Conditions

In some cases, chewing on plastic can signal a health problem. Conditions like hyperthyroidism, diabetes, anemia, or gastrointestinal issues can cause changes in behavior, including pica. If your cat suddenly starts chewing on plastic or shows other symptoms like weight loss, vomiting, or lethargy, a vet visit is essential to rule out medical causes.

Dangers of Chewing on Plastic

While chewing on plastic might seem harmless, it can lead to serious health risks for your cat:

Intestinal Blockages: Swallowing plastic can cause blockages in the stomach or intestines, which may require surgery. Symptoms include vomiting, loss of appetite, and abdominal pain.
Choking or Suffocation: Plastic bags pose a choking hazard, and their handles can wrap around a cat’s neck, cutting off breathing, as warned by Hill’s Pet.
Toxicity: Some plastics contain chemicals that can be harmful if ingested. Even non-toxic plastics can cause digestive issues if swallowed.
Dental Damage: Chewing on hard plastic can wear down teeth or cause fractures, leading to pain and infections.

These risks make it crucial to address your cat’s plastic-chewing habit promptly.

How to Prevent Your Cat from Chewing on Plastic

Stopping your cat from chewing on plastic involves removing temptations, offering alternatives, and addressing underlying causes. Here are practical steps to keep your cat safe:

1. Remove Plastic Items

Store plastic bags, containers, and wrappers in closed cabinets or bins where your cat can’t reach them. Be especially careful with grocery bags, which often carry food scents.
Cover or hide cables and cords, as some cats chew on these too. Use cord protectors or tape them out of reach.

2. Provide Safe Chew Toys

Offer cat-safe chew toys made of rubber, silicone, or cardboard to satisfy their chewing urge. Toys like the Petstages Dental Kitty Chew Wheel are designed for dental health and chewing.
For teething kittens, provide soft, safe teething toys to ease discomfort.

3. Increase Playtime and Enrichment

Engage your cat with daily play sessions using interactive toys like feather wands, laser pointers, or treat-dispensing puzzles. The Spruce Pets recommends toys that mimic hunting to keep cats engaged.
Add cat trees, scratching posts, or window perches to create a stimulating environment.

4. Address Stress and Anxiety

Identify potential stressors, like a new pet or loud noises, and create a calm space with hiding spots or a cozy bed.
Consider pheromone diffusers, like Feliway, to reduce anxiety, or consult a vet for calming supplements.

5. Regular Veterinary Check-Ups

Schedule regular vet visits to check for dental issues or medical conditions like hyperthyroidism or diabetes. A vet can run tests to identify nutritional deficiencies or other health problems causing pica.

6. Use Deterrents

Apply pet-safe bitter sprays to plastic items you can’t remove to make them less appealing. Products like Grannick’s Bitter Apple Spray are safe and effective.
Ensure any deterrent is non-toxic and follow the instructions carefully.

7. Monitor and Redirect

If you catch your cat chewing on plastic, gently redirect them to a toy or engage them in play. Avoid punishment, as it can increase stress and worsen the behavior.

When to See a Vet

While occasional chewing might not be a big deal, certain situations require veterinary attention:

Swallowing Plastic: If your cat ingests plastic, even if they seem fine, contact your vet immediately. It could cause a blockage or other issues.
Persistent Chewing: If the behavior continues despite your efforts, it might indicate pica or a health problem.
Signs of Illness: Symptoms like vomiting, diarrhea, lethargy, or loss of appetite could mean your cat has swallowed something harmful or has an underlying condition.
Sudden Behavior Changes: If your cat starts chewing plastic out of the blue, especially with other symptoms, a vet visit is needed.

Your vet may perform a physical exam, blood tests, or imaging to diagnose the cause and recommend treatments, such as dietary changes or medication.
