I've always had Stosh on Nature's Variety Instinct Rabbit and he ate reasonably well but not great. He rarely ate more than 3 cups a day, would no longer eat the frozen raw chicken patties. After much urging from my niece who runs the infirmary at the zoo, I bought a bag of Orijen LBP and mixed it 1/2 and 1/2 with the NV. We just got back from 5 days away and the woman that has the kennel where he stayed said he could not get enough food! He inhaled it and wanted more. I thought it was because there were other dogs around, it's gotten cooler, he was playing a lot, whatever. But it must be the food- I swear he's eating like I've never seen him eat before. And he's got so much energy, he obviously feels great, enjoys his food, wants more...can it simply be the food making such a difference?
