New owner question.

I've had my 10 month old CAG for a month now. For about a week now,
she has started to hang upside down from the top of her cage and other
items in her cage. Sometimes she seems to get scared that she can't
right herself and makes this horrible screaming sound, often while
hanging from one foot! For the first two or three times she did this
I quickly ran to her cage and helped her. Then I saw that as soon as
I placed her back onto her perch, she would put herself right back
into the same scary situation again. I thought that maybe she was
doing this as a ploy for me to give her attention, so I stopped coming
to her rescue and saw that she would eventually figure out a way to
climb down. Sometimes she'll repeat this four or five times in a row,
hanging upside-down from one foot, screaming, and then righting
herself.

I was just wondering if anyone else has seen this and if I'm maybe
doing something wrong. I give my CAG at least two or three hours a
day of close time with me, but obviously she would like more time out.

Just this morning while I was watching TV, I heard her making the
screaming sound and stood up to see if she was hanging upside down.
To my surprise, she was just sitting on her perch! Our dog starts
barking when she screams, so maybe the CAG is just having fun with
us??

Thanks,
