Just please BE CAREFUL!!! String, especially dental floss, can be dangerous if ingested. It can get wrapped around the intestines and do alot of internal damage.

Case in point: Shortie (my rescue Munchkin) has a fascination with dental floss. I made the mistake of leaving a piece of dental floss on my end table. I meant to throw it out. Next thing you know, Shortie was meowing and rolling her butt on the carpet. I always check their butts first when I see this. Sure enough, there was a piece of dental floss coming out her butt. I GENTLY tugged at it (DO NOT try to do this!) and a little came out. Up to the vet I ran. They gave her Laxatone and an enema until it finally came out. One very expensive vet bill later...she's fine. What an expensive lesson to be learned.
