The vet called and none of it was good news. The -- somebody medical help me out here -- BUN (?) and creatnine (?) numbers have both doubled, which is apparently a bad thing. He's dehydrated. He's constipated. He's going to need subcutaneous fluids daily from here on out.
I'm at work. I leave to pick him up in an hour, when I will be getting a refresher course in sticking a kitty with a needle.
I am in shock.
