Cats are known for their unique and often puzzling behaviors, and one of the most common and concerning habits is chewing on plastic. If you've caught your feline friend gnawing on plastic bags, containers, or other non-food items, you're probably wondering why they're doing it and how to stop them. As a veterinarian with over a decade of experience in feline behavior and health, I'll delve into the possible reasons behind this behavior and provide you with expert advice on how to address it.
Understanding the Motivations Behind Plastic Chewing

There are several theories as to why cats might be drawn to chewing on plastic. One possible explanation is that cats are naturally curious creatures, and their mouths are highly sensitive, making them prone to exploring their environment through taste and texture. Plastic, with its smooth and often crunchy texture, can be particularly appealing to cats. Additionally, some cats may be attracted to the sound of plastic crinkling or the smell of the materials used to make it.
Medical and Nutritional Factors
In some cases, plastic chewing can be a sign of an underlying medical issue, such as gastrointestinal problems or nutritional deficiencies. For example, cats with inflammatory bowel disease or food allergies may be more likely to engage in non-food chewing behaviors, including plastic. It’s essential to rule out any underlying health issues by consulting with your veterinarian and having your cat undergo a thorough check-up. A complete blood count (CBC) and urinalysis can help identify any potential health problems that may be contributing to this behavior.
Medical Condition | Symptoms |
---|---|
Inflammatory Bowel Disease | Diarrhea, vomiting, weight loss, and abdominal pain |
Food Allergies | Itching, scratching, and skin lesions |
Nutritional Deficiencies | Weakness, lethargy, and poor coat condition |

Environmental and Behavioral Factors

Cats are highly influenced by their environment, and factors such as boredom, stress, and lack of stimulation can contribute to plastic chewing. If your cat is not receiving enough mental and physical stimulation, they may turn to non-food items like plastic to satisfy their natural instincts. Additionally, some cats may learn to associate plastic with attention or rewards, leading to a reinforcing behavior.
Breaking the Habit
To address plastic chewing in your cat, it’s essential to identify and address the underlying motivations. Here are some strategies to help you break the habit:
- Provide plenty of mental and physical stimulation through play, exercise, and interactive toys.
- Offer a variety of textured and flavored toys to satisfy your cat's natural instincts.
- Keep plastic items out of reach, and consider using pet-deterrent sprays or bitter-tasting coatings to discourage chewing.
- Reward your cat for calm behavior and ignore them when they engage in plastic chewing.
