Please judge my mouse’s living situation and tell me how to do better

Hello all-

This is my deer mouse’s Pearl’s new house. She escaped her previous living situation which was not appropriate it was two of the critter trail biggest houses connected by so many tubes. Pearl chewed a hole through one of the tubes in a night and has been missing for a week. I just caught her last night with a peanut butter in a catch and release trap. so she is having her first day in this new living situation.

I just bought this house off of the recommended list here.

How can I better add to her living situation? What can I buy?

I never thought I would have a pet mouse or a caged animal so it’s hard for me to grasp if it’s ok - if she’s ok. What’s ok lol.

I wish I could release her but I have been told many times she won’t make it on her own. What can I do to add enrichment? She’s been on the wheel for hours now. I think she is definitely stressed.

Feel free to judge this is for pearls sake
