I just adopted an adult cat three days ago from a shelter. They didn't know how old she was because she came in as a stray. If I had to guess she is 3-5 years old.
When we offer her food she won't eat it. We have tried a few kinds of wet food but in the last three days she has eaten maybe a total of one can of food. When we open a can she will run up and take two bites then so purring and walk away. She won't even eat treats or lunch meat. She has also thrown up twice but both times seem to have been in reaction to beef.
Do I just need to keep trying different kinds of food for her? Is this just a nervous reaction to a new environment? (She seems pretty calm and happy). At what point should I be worried?
