In regard to the Cosimo saga I have to recommend a DVM in Rhode Island that caters exclusively to cats.
Dr. Katherine Lund and her staff at City Kitty are superb. I just wish office hours were a bit more convenient. I received a very nicely written card from Dr. Lund after I’d had to put Cosimo down.
So if you’re in the market for a good vet for your feline friends, and you happen to be in RI give them a call at 401-831-6369 (MEOW) or email at firstname.lastname@example.org or visit their web page here.
