My ferrets aren't caged although they are confined to two rooms (bedroom and bath) when we are gone. That is to prevent them from finding fiendish ways to torture the orchids that I also grow in the house. At night, they are restricted to the bathroom where they have a set of drawers that they sleep in and where their main litter box and food and water are kept. They are only restricted to the bathroom when my husband is home. For some reason he doesn't trust the female not to bite him when he's sleeping
. It just makes him jumpy I think although she never has done him any injury. She will come up on the bed though and stick her whiskers in your face or slither around down by your toes and wake you up.
