Hi Laurel,
I know that the Ferret Store sells them also. I have not bought one (yet!)
but they sound like a really neat contraption. Since I do not have one,
I cannot tell you how they work or anything. I just know that the Ferret
Store whom I trust, recommends them for ferrets. If you get one, let me
know what you think of it and how well it works.
