I’ve noticed some not so great behaviors the past few days with my squirrel Kiko.

Some background tho:
I’ve had her since she was a week old
She lives in a 3ft by 2 ft wrought iron cage
She gets 4 hours of cage free time a day
We live in MA

So the past few days during her cage free time she is very fixated on the window and looking for a way out almost the entire time and not playful at all. When I put her away to leave for work today, she started pacing at the bottom of her cage (like neurotic/ frustrated animals do in crappy zoos.) It broke my heart.

I know she can’t be released until the spring due to New England weather. But I was wondering if this would help: I have an empty indoor/outdoor chicken coop that I could add a heating element to and add reinforcements. My question is would this help her, or make her more frustrated? It’s not much bigger than her “cage free” area.
