Our 10 year old Siamese mix eats string, plastic, thread, fringe, rubber
bands, paper, ribbon, anything she can find. She has done this for years. We
try to hide or put away anything we see that we think she might eat, but she
always comes up with something, even if it's a little string from the
carpet. Consequently she vomits a lot - sometimes she throws up even when
she hasn't eaten any strange things.

She is a very high-strung cat, irritable a lot, but loving too.

Any ideas on what this is all about and how we can make her stop?
