Hi all. Last night, my cat started exhibiting a new behavior that seems to be turning obsessive very quickly. He started pulling at the fabric on his bed with his teeth, over and over again. He doesn't seem to be eating anything, but I'm not sure if that's just because he isn't really getting any fabric off. It was the middle of the night and I was exhausted, so the only thing I could think to do at that point was to remove his bed (he has other sleeping options) and eventually he ended up going over to his window seat and pulling on that fabric. He even tried to do it on my bed at one point. His bed definitely seems to be the most popular though (it is the softest). He threw up last night too, which I'm not sure was related or just a coincidence. Anyone seen anything like this? Doesn't seem to be a trigger for it, he just goes in his bed and starts pulling on the fabric. He's got a cat tree and a bunch of toys that I'd be totally fine with him chewing on, but he really just seems to be interested in a select few areas.
