I have a picky eater cat. One day he likes something and the next day I get "the look" when I serve it. Those of us who are "cat staff" know what that means.  ( Translation:I had that yesterday, I want something different today ). Although Max Cat makes a lot of flavors, this duck is the only one my picky cat will eat every day. In fact if I try to serve him something else now and then, I get the "smell and walk away" thing.  He now gets duck Max Cat every day and we're both happy! The other cats will gladly eat anything I serve, but they do love the duck the best. We do love our cats don't we?  Amazon's price is less than my local store too.
