Yes, I do not believe in letting ferrets run your home. It is way too dangerous and bad things can and will happen. When one of my ferrets was a baby she got a hold of an earplug for sleeping, chewed off a piece and ate it, and 1 very expensive surgery later...I learned to keep an eye on her and let her only play in a room that I have inspected. Now I have 4 ferrets and the room is a great idea, even if it is a small room, or a bathroom(with toilet closed) haha it is a lot safer than your whole house with electric chords, rubber, plastic, everythinggggg. They spend about 4-6 hours a day in their room, a couple with me playing with them, and then I let them do their thing and act like crazy ferrets.

If you are not paying attention to your ferrets long enough for them to escape, find your snakes, and figure out a way to get in their cages, something needs to change.
