Well, yay! I'm glad she didn't eat it, so that you don't have to worry about it.

My old roommate's cat was a horrible plastic addict. Bags were the worst, but given half a chance he'd also chow down on ribbon or anything else that presented itself. We had to be ultra-vigilant. I swear, if there was a bowl of food sitting next to a plastic bag, he'd go for the bag first!

Rizzo eats string. We discovered this when I left his favorite wand toy where he could get to it one day (yes, I know, this officially makes me a BAD cat mommy! I learned my lesson, though). When we got home, the wand was laying on the floor w/ a couple of inches of string attached, and the toy part was lying next to it w/ a couple of inches of string attached, and the rest of the string was nowhere to be found. This was a very long, thick piece of string. I don't know how he chewed through it, much less swallowed it. I watched him like a HAWK for two weeks after, looking for any signs of pain, illness, changes in litter box habits, etc. But there was nothing. I never saw the string again, either, so I don't know what that means. Maybe it was digestible. In any case, we've since caught him in the act of trying to eat our shoelaces several times, and a new, thin leather belt that came with a skirt of mine once. It's amazing how fast he can chomp through stuff like that. We really have to be on our toes and make sure everything that even resembles string is stashed out of reach.
