I have two adult pet rats. They are trained and spend most of their time in a cage. However, you'll need to let them out to roam for several hours in the morning and at night: apx 7a-10a and 6p-11p. They are very sweet and don't bite. Most of the time they'll just ignore you. You'll need to spot clean the cage, but the set up is very simple and quick. No big cleaning. You don't have to spend the might, but you can if you want.
