My neighbor’s cat has been technically abandoned and we have fed and cared for it for a long time. The neighbor is uncaring and said that he should have never bought the poor thing. She has been fine and is about 4-5 years old, but recently she has begun being sick every day. I believe it it is usually after she has eaten. I want to take her to the vets but don’t know if they will help her if she is not ours and the neighbor is certainly not willing to help out. What should I do? Do you know what could be wrong with her? It’s been happening for about a week and a half now. Thank you!
