Q: Why does my male cat like to chew on plastic shopping bags and newspaper protective plastic bags? My friend calls him “plastic man.”
A: No one knows for certain, but I’ve heard that cats enjoy licking plastic bags because they’re probably attracted to the tallow (rendered animal fat) that is contained in the plastic. Some hand and face creams contain extracts of farm animals, such as collagen, and cats will occasionally lick at these.
I had a cat named Emma who used to love to lick photographs. Photographs contain an emulsion that has gelatin, an animal product, as one of its ingredients, and Emma loved the taste of it.
Keep the plastic away from your cat. If swallowed, plastic bags can cause an intestinal obstruction that can make your cat very sick and may even necessitate surgery.
