"I'm really glad I discovered this food. My two cats had been having trouble with hairballs and constipation. Their vet recommended that we stop feeding them dry food and just give them canned food, mixed with a large spoonfull of canned pumpkin. It has made a remarkable difference and improvement in our lives. After two weeks of this new diet, their coats feel and look softer and glossier, they seem happier and more spunky, and we haven't had any messes on the carpet at all. We used to get them almost every day. I'm really happy with this Science Diet product."
