Do you think she would ever realize she's not going to catch the bird, and would stop? I also have a pretty big cage for a cockatiel, it has very heavy bars and is on a stand by itself (you could probably fit 4 cockatiels in it with no problems).

What about a cage that hangs from the ceiling? Or what about rearranging furniture?
Sorry, but what's a scat mat? Maybe that'll work if we give it a try, depending on exactly what it is.
