It's a little-known fact that in addition to two dogs, our bosses also have two rabbits. They generally keep to themselves and have three substantial habitats where they hang out. They also have a section of the boss' home where they run free.
The big question: don't they make messes everywhere? Never! Not once. They're very clean and do their business in the same spot every time. It's never, ever been on furniture or the floor. Ever!
