At the suggestion of a few people I bought a bag of this for Neiko and Lily. I had some serious sticker shock though with it being $52 for the largest bag. 
I'm half way through the bag though and have to say that it's lasting me longer than any other food we've tried. Lily (42 lbs) only gets 1 cup per day (instead of 2 with other brands) and Neiko gets 2 cups per day (instead of 4). I might even cut Neiko back to 1-3/4 cups per day.
Neiko is doing well on it. This has been the only food (besides Total Performance - similar price with delivery) that has enough calories to sustain him. It is giving Lily gas though. I think it's too high in protein for her so I will probably switch her back to Canidae or something similar.
