Buster is the hardest bird to keep his cage clean, not only through dust and his destructive nature but every thing goes every where, He is so loving but his grip dose leave holes in my hands and arms, part of that is my fault as I do not trim his nails as he dose free fly and if he ever gets lost he will need to be able to scratch for food and also defend him self. the cleanest bird I have is by far is Oliver he hardly makes a mess poops in one place, ets all his foods and keeps any shells together in the bottom of his cage, Water always clean apart from when I add a little bird clay , very surprising as he is an Double yellow headed amazon, I am sure he has OCD Ha ha,
