3- Any other symptoms?

Please give me a few minutes to type your answer. Thank you.
Friend, not eating is a very non specific symptom and can be related to many different medical conditions that affect cats. In cats as a species regardless of the underlying cause when they stop eating they will develop liver problems (hepatic lipidosis). The fact that she vomited after you feed her a small amount of food further supports an underlying medical problem. Unfortunately in this case we are very limited as to what you can do at home. To determine the exact underlying cause she will need a hands on examination by a veterinarian and some blood work as initial screening test. Treatment will be based on exam and test results. I would strongly recommend having her checked by a veterinarian as soon as you can. In the meantime wait a few hours until you offer food again. Next time try a bland diet like rice with boiled boneless chicken or ground beef. If possible blend the food and give her small amounts with a dropper 4-6 times a day.
