they are an amazing amount of work. I think most people up for that work get toddlers instead.
loved them when I had them, no longer have the energy.
the leash was always more a reminder there were limits than any sort of control option. throw that weasel in reverse and the harness pops right over the head and he's free.
As a current ferret owner, I empathize with this comment so much. I do take mine out on leashes, one at a time, every now and then, and it takes a lot of patience and energy to do so. But it's always great when I get to show people pics or vids of my ferrets on leashes. It always gets a great reaction.
