When something really interesting = bad, happens on PT, I send the thread to my vet and ask him for advise. I did when Bassett and Binx were so sick. He always replies, and he's very eager to help if he can. Unfortunately he couldn't. :( Anyway, it's nice to have a vet you can chat with like a friend. :)
Bwt, he has an orange tabby. :D
What's your vet like?
