But prescription diet is expensive, and in case the problem was resolved (or if the problem had just been worms in the first place), we called the vet clinic last week to see about transitioning him off the prescription diet onto some new food. They were really helpful and recommended some good foods, and so we picked one and started mixing it with the last of his prescription food, to ease the transition.
That worked great for about 6 days. Then the night before last, Pan threw up a tiny bit in the middle of the night, and I got worried.
Last night, Pan threw up what looked like everything he had eaten in his entire life. And this morning, he's thrown up twice more, both times after I fed him the last little bit of his prescription diet, unmixed.
The extra twists in this is that Pan sneaked downstairs to my Mom's last night and tore open an entire bag of cat treats and ate them all. And this morning, the first time he threw up, I found a wadded ball of stuffing in it, from one of his cat toys.
So, I don't know if he is throwing up because his stomach is unhappy about the food change, because he scarfed an entire bag of Whisker Lickins', or because he had a big wad of stuffing in his stomach. And, as usual, the day of the week he picked to be sick is Sunday, when the vet is closed.
I'm now totally out of prescription food and I can't get more until I go to the vet, so he's not getting any more food until the rest of the day, and I'll call the vet tomorrow.
The really annoying thing about all this is that in the month of prescription food when Pan was totally fine, he was here in Seattle, and we were at Taylor, taking care of a 6-month old golden retriever puppy who kept eating coyote poop and her chew toys, then cheerfully vomiting them up in the middle of the night.
I cannot express in words how ready I am to be done with vomiting pets.
