If Beebs is with you and Amy is permitted to sit on top of the cage, is she content there?
I'm just thinking, if it is an attention thing then being on the cage without any attention from you would not satisfy her desire to be on top of the cage. So then some other attention-seeking behavior would likely follow, if I'm thinking along the lines of a Zon brain...
But the fact that she is content with you in another room, makes me wonder if it is because she is getting the attention she wants from you or if it is more of an out-of-sight, out-of-mind type deal.
I'm sure it is frustrating though. Mav has been on a screaming kick this week. We were out of town for 8 days and got back this weekend, so I'm pretty sure it is punitive. But it drives me crazy to wait patiently for him to stop screaming so I can go get him and reward and resume whatever I'm doing.
They drive us crazy with their stubborn little brains!!
