The cat is home now. She's doing better - apparently the daylong treatment was a combo pack of a more powerful antibiotic, rehydration, and treatment for out-of-whack phosphorus levels.

The vet fed her tuna. And babyfood ham. Neither of which she EVER gets, so that probably made the stay a little less onerous. My mom said the cat looked better - that apparently she was dehydrated and that was what was causing a lot of the problems. She did get sent home wearing a funnel collar (because the iv port is still in her paw), but my mom said she took it off and instead put a small piece of soft cloth over the port, because she figured it was unlikely the cat would mess with it, and besides, she figured the cat could not eat or drink with the collar on, and she really does need to continue taking in water. At the very least.

She does have to go back tomorrow and I guess based on the results of a blood test, she either gets to go home with more pills, or she gets another day of the antibiotic drip. I'm hoping the conclusion is that she's better enough just to go back home, but at least it sounds like she's doing better for now.
