I think my cat is sick but I'm not sure. She is 14 months old and she is usually running around and jumping but all of the sudden shes been sleeping and it seems like shes avoiding any walking (I think maybe her body hurts). Shes also hasn't been eating her wet food as much and doesn't want to drink any water and I have to force her. This morning she was laying down and meowing a lot and I looked at her and she started growling which she never does. What's wrong with her?
