I have been feeding Wysong Anergen for 2 months now. The size is not much better than Royal Canin-but it's a wonderful food. Ralphie was only 2 lbs when I got him He really likes this food, and he is now 3.5 lbs at almost 6 months. I got mine from a good pet store, but I notice that Hi Health Health Food Store is now carrying it. Also found it on line. I give it 3
up!
