I'm so sorry to hear that your little fuzzbutt is in need of surgery for a lump on his tail. My roommate had a little fuzzbutt that also had a lump on his tail and the vet had removed half of his tail, and that never slowed the little critter down one bit. So i am pretty sure that you have nothing to worry about. I wish you and your little baby the longest happiest life. [LG] [Posted in FML issue 5021]
