I would say ferrets are my favorite non-traditional pet. I had two growing and they were so fun and full of personality. They had a large cage that I would put them in at night (sometimes I let them sleep with me) but during the day they were mostly roaming around. They are kind of like kittens that never get old. They sleep a lot but when they wake up all they want to do is play. When you have two together they run and chase each other and play fight. They can be hard to care for though. You can litter box train them but mine never seemed to get the hang of that. They would poop in the corners instead. Sometimes they had a favorite spot and they ruined the carpet we had because sometimes they just go wherever they please. They also have a musky smell, which I didn't really mind but it may bother others. I miss my ferrets but I don't know if I'd own them as pets again.
