My cats love treats. (Who doesn't?) Typically I buy them whatever treat happens to catch my eye at the store and is reasonably priced. They like them and will often come back for more, BUT when I fed them the Fancy Feast Duos, not only did the come back, they RAN back. They were even territorial about "their" treat, not letting their housemates even close. I fed them a lot, even for me, and I finally had to shut them off or they would have eaten the whole bag. I love the Fancy Feast brand anyway; that's what my cats typically eat, in dry and wet, and these Duos (especially in the tuna flavor - I have no idea if they even noticed the parsley!) are just the icing on top of the cat cake!
