He got Feline Distemper FVRCP.
The vet techs said they tried to draw blood to do blood tests but couldn't get it. Maybe they injured him trying to draw blood? Is this the location to draw blood?
My new cat went to the vet three days ago and got a vaccine. I was looking at his legs today and noticed significant bruising and a welt. There seems to be a gray spot in the center of the wond. Is this normal?
