Louise I just read about your vet hospital in the other thread, and it sounds like you are in such great hands, so its worth every cent. Sending you and your kitty lots of healing vibes.
When I was a vet nurse, I hated anything dental at all - it was the only type of procedure that would make me queasy - I'd rather an amputation or bowel obstruction surgery than a simple tooth extraction! I'm even getting scared now because all the kids in E's class have started losing their first teeth and I don't know if I'm going to be able to cope with seeing a wobbly tooth!
