I got Nala, a white 4 years old Persian female cat two months ago from my vet. He toldf me that her family left her for another loving one. She is cute and I was assured that she is healthy. In the first week she was shy and stayed away from Ginger and her daughters. I noticed that she refuses all kinds of food except the dry one (Purina in particular). I tried with her all different food types. The only time she ate a different food was last week when she ate cooked chicken liver. I am afraid that it is not healthy for her. I checked with the vet at first week and he told me that she will be OK. Any advice.
