I switched everyone to PANR last year. I was feeding Mazuri, I have no idea what crap people were feeding them before they came into the rescue. There were a couple of reasons for my switch: 1) After having a surgical staple removed from Lily's stomach, she wasn't interested in pellets at all, I tried a bunch of different kinds and the PANR was the only one she was interested in eating; 2) During the time that Lily was eating PANR I had a couple of pregnant chins come in and put them on PANR, they were really healthy and had some good sized babies; 3) the price of Mazuri jumped from 25lbs/$16 to $30; 4) with 25 rescues, it's easier to have everyone on the same food if I can.
