Too cute, PA, have fun.
A friend of mine took in a baby squirrel who fell out of a tree and the parents never rescued her. They raised her indoors and got her a huge cage with real tree branches inside (and a sling bed and toys) and she was another family pet. They gave her a hamster ball for being loose in the house, until she outgrew it. When the weather warmed up, they put the cage outdoors. And when they moved, they built the cage around a real tree, so she could climb it, but she was still confined. She figured out how to open the door repeatedly, so they left it open and she'd leave and came back to hang out in there and get supplemental food.
She found a mate and had babies and still comes around.
