My sister has 2 very big male cats. They are a little overweight but not as much as people think. They are just very very big cats. They are also very picky cats. One had a urinary tract blockage and now occasionally starts having problems with urinary leakage that goes away with pain killers. They were put on wet food because of that. However they keep getting tired of wet food and after going through all the wellness flavors are refusing food again. Prior to that they started refusing evo. They actually prefer dry food to wet food. I'm going with my sister to a few stores to look at various pet foods available. Do you think she could go back to dry? Any brand suggestions for wet or dry?
