I am sorry to hear Thumbs isn't any better
I know it sounds scary about the FIP but throughtout my lifetime with cats we have had 2 cats with FIP (about 20 yrs apart)...none of the other cats caught it. And the last one to have it Paulie, he was a sweetie and he would wash the kittens we had at the time before we found out he had FIP and they didn't get it. One of those kittens we kept and he lived for 10 yrs and passed from Renal Failure.
