Thanks everyone. From Kater's link, check these out!

The elastic collars worry me, I guess. My RB kitty Boo got his jaw around a collar when I first put one on him. Luckily I was there and took it off, but if a collar stretches I can see many ways a cat could get a jaw or maybe even a leg stuck in an expandable collar - and really get in trouble.

Here's a Hanna picture I took this morning - she was laying flat on her back with her legs up and had the dopiest look on her face, but when I grabbed my camera she moved. Oh yeah - she has claimed that dog bed as hers.
