My room is 100% secure. There’s no wires, things it can chew, etc. The rest of the house is not. My setup is secure enough for a normal ferret but I doubt it’s secure enough for a hybrid since you said they can jump high. And I also assume that they have more accidents than a normal ferret. They’d definitely be a cool pet to keep with the right setup. Kudos to you for being able to do it.
