Do you now where I can get the holders for 2x4's for the cages? I've never seen those. I think they would help her lot. Now they are just pushed through the bars and hanging out. I'll look into getting her some more 2x4's as well, she's overdue- I think only two of them have the whole piece left. I really want to splurge and get them some natural perches for them, but that would be LATER in my budget.
