Spartakiss has PICA pretty bad. He tries to eat everything. Plastic bags, paper, ribbons, string, everything. He even chews on the couch. Is there anything I can do to stop this, or is it something I'll just have to learn to deal with?? I'm just so worried that one day he's going to get into something really dangerous. I try to keep everything off the floor, and I have cupboard locks, but he still can eat the couch and I might always forget something.
