Errie was across the room from me, crouched behind a cardboard box, so I couldn't see his feet. He was acting strange, and at first I thought he was stalking something, then it started to look like he was just twitching and he looked unfocused and distressed.
Just as I got up to go check on him, with visions of seizures and all kinds of dire possibilities running through my head, he got up with a bit of a popping noise, and strolled off normally.
Apparently he had a claw hung in the carpet. *rolls eyes*
I really need to relax... really...
