Bests & Worsts Reviews from Amazon

My cats thrived on this food for a couple of years until the recent formula change. Now two of them are vomiting frequently and dealing with nausea and a third had to be moved onto wet food because she started having urinary crystals. I hate that they've changed such a great food and added ingredients which apparently to which a good portion of cats react negatively. Unfortunately I bought three bags at one time and now I'm stuck with two bags of cat food which my cats shouldn't eat!
