Why Is My Cat Obsessed with Licking Plastic Bags?
You’ve just unpacked the groceries, and before you can even put the bags away, you hear it. That distinct, rhythmic crinkling sound. You look over, and there’s your cat, eyes half-closed in pure bliss, aggressively licking a plastic Target bag.
It’s weird. It’s annoying. And honestly, it’s a little concerning.
If your cat treats plastic bags like they are coated in catnip, you aren’t alone. It’s one of the most common—and strangest—feline behaviors. But why do they do it, and more importantly, is it dangerous?
Here’s why your cat is obsessed with plastic and how to get them to stop.
1. It Actually Tastes Good to Them
Believe it or not, your cat isn't just licking the plastic for the fun of it; they might actually be tasting something.
Many modern plastic bags are manufactured using animal by-products like tallow (rendered animal fat) to make them easier to pull apart. Others are treated with cornstarch to prevent sticking. While we can’t smell or taste these subtle ingredients, a cat’s highly sensitive nose can pick up on them instantly. To your cat, that grocery bag might literally smell like a faint, savory snack.
2. The Crinkle Sound Triggers Their Prey Drive
Cats are predators at heart. In the wild, the high-pitched, crinkling sound of dry leaves or grass usually means a mouse or a bug is scurrying by.
The crinkly noise a plastic bag makes when a cat licks or bats at it mimics that exact sound. It engages their natural hunting instincts and turns a boring piece of trash into an interactive toy.
3. Pica and Nutritional Deficiencies
If your cat isn't just licking the plastic but is actively chewing on it and trying to swallow it, you might be dealing with a condition called Pica.
Pica is an eating disorder where animals compulsively eat non-food items (like plastic, wool, or cardboard). In cats, Pica can sometimes be triggered by an underlying medical issue, such as a nutritional deficiency, dental disease, or gastrointestinal problems. If your cat is a plastic chewer, it’s always worth mentioning it to your vet to rule out any health problems.
4. Plain Old Boredom or Stress
If a cat is under-stimulated, they will find their own ways to entertain themselves. Licking plastic is a repetitive behavior that can be self-soothing. If they are feeling anxious about a change in the household (like a new baby or a change in your work schedule) or just don't have enough toys to keep them occupied, they might turn to the grocery bags as a coping mechanism.
How to Stop the Behavior (And Why You Need To)
While licking a plastic bag might seem harmless, it can quickly turn deadly if your cat accidentally bites off and swallows a piece. Plastic cannot be digested. If swallowed, it can cause a severe intestinal blockage that requires emergency, life-saving surgery.
Here is how to break the habit safely:
Remove the temptation immediately: This is the easiest fix. As soon as you bring groceries home, unpack them and hide the bags in a secure drawer or take them directly to the recycling bin. Don't leave them out on the counters or the floor.
Provide safe alternatives: If your cat loves the crinkle sound, buy them dedicated cat toys that have crinkle paper sewn inside.
Grow some cat grass: If your cat has an urge to chew on something textured, buy a small pot of cat grass (usually oat or wheatgrass). It’s completely safe, great for their digestion, and gives them an appropriate outlet for chewing.
Next time you hear that familiar crinkling sound, swap the plastic bag for a toy. Your cat gets to play, and you get peace of mind.
