Plastic wrap, bottles, my notebooks, if it's plastic they will try to eat it despite having a full bowl of food.Halp.
One of my cats bites on plastic, specially in his plastic bowl, but after he is done eating.... Anyways he tries to bite in plastic bags, cardboard boxes and so on.... just be careful and keep those items out of your cat reach !!!
It is not exactly known why some cats like to eat plastic, but one theory that makes sense to me is that it's because rendered animal fat (also called “tallow”) is utilized during the manufacture of some plastic bags, and that some cats can detect the smell and enjoy the taste. As I'm sure you're aware, plastic is very very dangerous to cats. It can block off their breathing way or get stuck in their gut and cause a blockage. Please be very vigilant about keeping plastic away from your cat. Store grocery bags out of reach (inside drawers or some other closed off place). When you open packages dispose of plastic immediately. This isn't something that you can just fix - the best answer is continual vigilance. Soon it will become habit to get rid of such things right away if you consciously do it at first.
Do your cats actually eat the plastic or do they just chew on it? Many cats chew or gum plastic. As others have said, one theory is the materials used to make the plastic attract the cat. If they are just chewing or gumming the plastic and are not actually swallowing any, no problem. If they are actually swallowing the plastic, problem. If they are actually swallowing the plastic it could block their GI tract. But -if the pieces are small enough, I would suspect they will pass through the system and be passed in the stool. If they are swallowing the plastic - call your vet for advice.
