Cat has stopped eating (now on 3rd day) and seems very unlike herself. Doesn't want to be around me, a bit withdrawn. I took her to the vet yesterday, at which point she stopped being lethargic and became downright cross - to such an extent that they couldn't examine her properly, but said her teeth seemed fine. Gave her an anti-emetic injection in case she wasn't eating because feeling sick and told me to tempt her with strong smelling food. I've been trying that and its not working at all. Her response to me putting a bit of catfood on my finger just now and putting it near her nose was basically to recoil from me, as well as swishing her tail a bit. She's now gone to hide under the bed. I can't work out if she's stressed about something or unwell. Any thoughts??
