I agree with what the others said about stress and the unfamiliar food potentially causing things like this. Cats are so sensitive!
When Edwina had her disgusting vomiting and mucous episode in December (apparently caused by eating a plant--probably not Ghibli's problem but still...) the vet suggested feeding baby food first. That seems to be a common recommendation for stomach issues. I bought Beechnut Classics, which were just meat and broth. Both cats ended up liking those with PureBites! After that, I fed her low-calorie canned foods and didn't start her back on raw stuff for a couple days. The vet also gave her Cerenia.
I hope the vet appointment goes well! Fingers crossed!
