Thanks again, all.

One odd thing the vet told me that may relieve some of you, too. Apparently cat's platelet clump VERY easily. Part of the reason it took soooo long to get the results was that when they did the initial platelet count they did it by machine to be faster and due to the clumping he showed up dangerously low. So they reran the test manually and he was fine. I'd no idea about this. Had any of you heard of this before?
