Ferrets spend 14–18 hours a day asleep and are most active around the hours of dawn and dusk, meaning they are crepuscular.[8] Unlike their polecat ancestors, which are solitary animals, most ferrets will live happily in social groups. A group of ferrets is commonly referred to as a "business".[9] They are territorial, like to burrow, and prefer to sleep in an enclosed area.[10] @Curionic
