Hey Cass!

My RB Tier did that for a little bit. It got progressively worse though (he was hurt) and he ended up having to go to the bridge. The vet had asked me if he was an outside cat. I told him no, never a day in his life. I guess he had "broken his back without actually breaking it" and it basically boiled down to some disorder he'd had his whole life, apparently.

*HUGS* Lots of FANTASTIC thoughts your and Meow Meows way! He's a good widdle boy!
