My roommate in college had 4 and then 5. They were fun, but she didn't watch them and they would wreck my stuff, dig up my plants, and hide my keys. She couldn't understand why I was so upset when I'd come home with a date and there was potting soil flung all over my room.Females will go into heat and stay in heat until bred. They can die if not bred.
Not sure if it’s illegal to have them intact. But I don’t think you could stand the smell. My male smells worse than my female. He’s got a stronger musk smell. My female isn’t near as bad. They are both fixed. They are the first pair of ferrets I’ve had. Two are definitely more fun than one lol
