I have a question for you about bunnies. My friend has a chinchilla bunny who is so cool!! HIS name is Guen (they thought he was a girl at first) and he's 3 years old.Anyway, he keeps getting these ulcers on his back legs near the bone joint. She has a
cage that does not have a grated bottom (the vet recommended a smooth bottom).

Try putting something softer in the bottom - many people get carpet remnants for their bunnies cage, or put hay down. Miss Hoppy has maize mats in her cage - not that she stays in there much, she's free to roam, but I buy them by the 1-foot square at Pier One . This was recommended by other bunny folks, and they're great! She lies on them, chews on them, eats them - we have a few on the kitchen floor for her to relax on, too!

And FloppseyLadySally - do put at least a piece of cardboard in Floppsey's cage for him to have something that's not grating to rest on - life in a wire cage can cause problems for a bunny in the long run - sore on tehir feet, etc.
