Strange climbing pattern...

Lola is allowed out of her cage whenever someone is home,  which usually ends up being from 3pm until her bedtime around 8:30. Every night, for the last 4 nights in a row, she has began climbing in a specific pattern, repeatedly, after being closed in her cage for the night. I can't find any information on this anywhere, so I'm definitely curious as to why this is happening..

This went on for over 15 minutes. She has me stumped! I'm not sure how to respond, or whether to just ignore it.
