I have never used it yet, but I have studied it for a few years now, it APPEARS to be great food. I have known a lot of pet owners and shelters who have used it succesfully.
It's suppose to be one of those all natural meals.
I have used the Wysong Vitality in the past...my cats seemed to like it but also seemed to shed quite a bit more while they were on it but its also possible that it had nothing to do with the food. I have also used the Archetype (just as a treat) which my cats and dog loved dry but wouldnt touch once I moistened it and the All Meat cans which is a nice little treat for them on occassion.
