Things have been a little better. After the zofran last night she did not throw up again. I gave her another dose 8 hours later and she ate a little bit of dry food - a few bites. I made her wet turkey, she refused, so I made her some freeze dried rabbit and she ate that. But then wouldn’t eat it again 4 hours later. Did another dose of zofran (8 hours later) and made her more rabbit which she said no to again. Tried the ziwi venison, nope. put a little mirtaz in her ear and she ate a few licks of wet turkey about an hour later. She has not thrown up at all but has been very lethargic, just sleeping all day. We gave her the last dose of amoxicillin this morning and am now hoping that once that’s out of her system she might start feeling better. I googled today that amoxicillin can cause appetite loss, nausea and vomiting Along wit diarrhea and gas. Maybe her system is just now having reaction after it built up in her system for 8 days. Maybe it killed what it needed to which made her feel better but then then after there was nothing left to kill, it just upset her tummy by being constantly nuked. at least she’s not throwing up. Tomorrow I hope we wake up to a kitty with an appetite. How long does it take for antibiotics to leave their systems. It’s been nearly 12 hours since her last dose.How is she doing today? Any change from yesterday? Poop still pretty good? If she is still vomiting, maybe try feeding her plain meat baby food, or some plain poached chicken (no onions, garlic, that sort of thing) to see how she does with it. I honestly don't know what else to advise other than give your regular Vet a call on Monday about it,unless you want to take her to an emergency Vet if she's unable to keep ANY feed down even with the Zofran on board. Hoping things are actually a little better today.
I don't know if it is a common problem with the British Shorthair breed in particular, but I do know that cats with a higher level of inbreeding can tend to have digestive and immune system issues. Did both cats come from the same breeder? Have you talked with your cat's breeder about the problems you are having?Auggie is the same breed, British Shorthair, I wonder if this is common with the breed?
