"My fuzzies *love it*. We love it, too, because we can see everything that's going on in there. If you've never seen a ferret wag it's tail very quickly when they're excited, get this tube, and you're bound to see it! Our four stinkies spend most of their awake time in here. Unfortunately, it gets torn up pretty easily (though not as easily as the foil dryer tubes you get at the hardware store). We have to coat the ends with duct tape b/c the fuzzies like to chew them up. They also rip holes in the middle of the tube sometimes (so they have emergency exits I suppose? hehe). We have to buy a new one every couple of months, so we're going to invest in those hard plastic, buildable tubes next time. They're more expensive, but they appear to be indestructible, so maybe they will be a better investment."
