You can start by keeping all plastic bags and other things (bottle rings, etc.) out of his reach. I had a cat who loved the plastic shopping bags with handles. There is something in the processing of them. They use some kind of animal oil. Anyway, he got his head stuck in it one time and was flying all over the house. Fortunately I was home. I keep anything plastic out of their reach. Obstructions can not only be costly but also dangerous.
