I knew that cats' blood clumped easily and that is why, if they get any kind of puncture wound it sometimes becomes abscessed, because the blood clots too easily then the sore scabs over and basically heals from the outside in, trapping the bacteria in and causing infection so the wound needs to be re-opened, drained and allowed to heal again after being cleaned out.

I had no idea it affected blood tests, but I guess we know now.

It's great that you need to type around him again. Awww....
