I'm currently feeding mine purina but I did some research the other day and found many complaints about it and found out that it's not very healthy. I'm looking for something that my cats will love, but also something that is not tested on animals. Or at least something that is only tested in cage-free, in-home situations. Thanks!

My vet said Purina is OK. But I still buy the one from the vets, it's called Hills, something like that.
