Well, Nova is back from the vet. They ended up keeping him two days and letting him go this morning, saying he seemed to be doing better.
But, oh, man. You know, when I picked him up this morning, I thought he smelled kind of bad, but I was half asleep, having just worked all night on too little sleep, so, after making sure he'd had something to eat, I just staggered into bed. This morning, I got up and realized he didn't just smell bad, he smelled really bad. The treatments they gave him to get his bowels running again clearly did something, because his entire back end was covered in crap. It was awful. It was so bad that when I tried to feed them, before I realized what the problem was, Vir just hissed and refused to stay in the room with him.
And now my entire house smells like cat crap. Especially the sofa and the spots on the carpet where he likes to sit. Except, of course, for the part of the house that smells like the bleach I used to clean the tub with after I washed him off. Which, needless to say, he did not like any more than I did.
It's a good think I like these animals, that's all I have to say.
