Genia,
What special people you and your vet are for doing everything possible to save Tigger. At least he felt all the love you could give him. I had a Tigger for 18 years growing up. He was a holy terror for the first few years of his life, but a very special cat.

On the subject of Butter...his hair will grow back, right??? I feel so sorry for him, but he is feeling much better today!!
