Hello:
I have some questions for you:
Awaiting your reply.
Is she urinating and defecating normally? Increased or decreased?
I become concerned when a cat doesn't eat for more than 24 hours. The body goes into starvation mode and the liver can get overloaded and result in a condition called hepatic lipidosis or fatty liver.
If she becomes dehydrated, her kidneys could be affected.
If she does not seem to be getting better by tomorrow morning I recommend getting her into your vet.
Let me know if you have further questions.
