Budzilla, our 32-year old sulfur-crested cockatoo is fed only the Harrison's brand because it is certified organic and non-GMO which is a nutritional criterion for our household. Budzilla does like to occasionally play around and fling a Harrison's nugget or two up in the air, but he does enjoy his high potency food and does well on this diet, he is healthy, and has full "plumage." He's been dining on Harrison's for many many years.
