Cat tooth diet

My cat initially would not eat it, but then, she decided she loved it. It's healthy for her teeth so she gets a small amount each evening to help clean her teeth,

My cat initially would not eat it, but then, she decided she loved it. It's healthy for her teeth so she gets a small amount each evening to help clean her teeth, and she still eats her other dry cat food by hills and enjoys it all.

Very satisfied

After administering meds to my rescued cat for upper respiratory infection and giardia her diarrhea would not subside. Not sure what combination of ibd or food

After administering meds to my rescued cat for upper respiratory infection and giardia her diarrhea would not subside. Not sure what combination of ibd or food allergy possibly involved, but feeding only this particular salmon and rice version for a week seems to have helped firm stools up noticeably.

Gave my sick cat longer time with me

My cat had fluid buildup from kidney failure, and this food gave me a year with him before he started having pain and had to be euthanized. He was a very picky

My cat had fluid buildup from kidney failure, and this food gave me a year with him before he started having pain and had to be euthanized. He was a very picky eater and refused to eat any other foods even tried other science diet flavors. This is the only food he would eat. He was such a good kitty. I miss him so much but at least I had extra time with him.

Best diet food ever!

So this is supposed to be diet food for my “full figured” lady felines; but they’re eating it like it’s full calorie food! I can’t keep the bowl filled up! Plus
