Help please, Violet is a small 13 year old cat, she was sick on Monday several times, after the first few times just bringing up bile, vet on Tuesday who gave painkiller and antibiotic, she will not eat and is drinking very little just sitting/sleeping in her bed. She brought up more bile an hour ago. She looks fine and I stroke her but can not get her to eat, which I know is OK but she also is not drinking. She is not stressed as in the room with her sister, warm and quiet, I will take her to the vet again but wonder if anyone has any ideas?
