I nearly bought their grain free food because it’s supposed to be one of the best. EVO was yanked off the market for some reason, so I am using a different brand, but I strongly suspect a lot of them do things like this. If it weren’t for the fact that the tummy issues disappeared thanks to the grain free food, I would think it was all the same. Lord knows it all smells the same.
