"I got my cockatiel 3 years ago, and he was fat, sickly, and on a seed diet. My vet (also an avian specialist) said that I absolutely had to switch him to a pellet diet.
WELL - I tried several brands of pellets, mixing them with seeds, leaving out seed completely (the Vet's assumption being that my bird would eat before it starved itself - I did not trust this, since he went several days without eating), and then switched to ZuPreem. He would at least put them in his mouth, but wouldn't eat them. I tried fruit, then realized my bird liked fresh veggies better, so tried garden goodness, which went better, but he avoided all the colored bits.
THEN I found this, and my birdie pounced and has never gone back. He LOVES this natural pellet diet, and is incredibly healthy and happy.
Thank goodness someone at ZuPreem realized that not all birds want to be visually stimulated while they eat. Mine is so happy to eat nice, normal colored food. :-)"
