Jeez, I'm the whacko here...
Every two months on the nose I take everything out of the cage for a deep clean and reorganize everything--toys, perches, boing. I really enjoy it... I don't know why. I just like the challenge of keeping it interesting. The only thing that never REALLY changes is food bowls--they just switch sides. I like keeping them on the bottom of the cage--lowers the fling radius. 9__9
