Squirrels are not cage animals. We were fortunate enough to have a large area that was protected. Dr. Mom would have killed before she'd have given up that little critter. Squirrels hate winter. She leaped up, shook herself, looked at us like we had lost our minds, and dove back into her bed.
Squirrels are clean.
They spend a lot of time grooming, especially their tails. On one occasion as Dr. Mom was making breakfast with Friday on her shoulder, Friday decided to jump on top of the fridge. At that moment Dr. Mom turned and Friday dove head-first into a pitcher of orange juice. That took a lot of grooming, but at least it was something she liked. And they know how to use them.
