Back from the vet's.
Bloodwork didn't show an elevation in eosinophils. In fact, the number had dropped since October. It's possible that there was an allergic reaction that hasn't been around long enough to elevate said eosinophils, but at this point, vet is leaning toward a dietary misadventure that hit Gaby like a ton of bricks.
That being said...vet recommends trying to feed her hypoallergenic food, given her history. As a back-up, we may try rabbit since Gaby has to our knowledge never been exposed to that particular protein. I don't believe she would have been, unless she killed and ate a wabbit. Possible, but.
Another possibility is irritable bowel syndrome. If this doesn't resolve, or if it happens again, we will likely go the biopsy route to confirm/rule out once and for all. It's a manageable disease. Vet told me that she treats a cat that flares once or twice a year, and needs to be treated with a steroid to quell the inflammation. Then it's fine for months.
Vet and I are also wondering whether this food/GI issue is the reason her previous people gave her up. She kept getting sick and not eating, and they didn't have the wherewithal or the patience to figure out what was wrong with her. There had to be a reason why she was almost 10 pounds underweight when she was turned in to the vet's office when she was apparently not a stray.
Anyway. Gaby had sub-q fluids and a shot for nausea and a couple more shots to quiet her tum. Later, I will give her a tablet for the diarrhea--she'll be on those for about a week. Hopefully, she'll eat and keep it down. If she had another bout of the runs, I'll deal.
She's sleeping now. Poor thing tries to bounce a little, then lies down and dozes. She's had a rough couple of days. I came home today to find that she had been sick again--more vomiting and diarrhea. Took a sample of the d-word in just in case the issue was a parasite, but it wasn't. We'll work on getting an answer one way or another.
