My husband and I have some of the heavy clear dust collection hoses. They are WONDERFUL!! The really heavy, and more expensive hoses are so tough that you can stand on them and they won't bend. We have one that we've had for a few years and there is not a puncture anywhere on it. One of the extra benefits, other than lasting forever, is that they are quiet. We run a small rescue from our home and when the littles are out playing in the super pet tubes you hear the click, click, click of tiny little toe nails everywhere. When they run thru the dust collection hoses you don't get that sound. A less expensive place to get the tubes is at the Woodworker Shops. They run approx. $30 for a 10' section. Those aren't the super thick tubes but they are still quite a bit thicker than dryer hose tubes. We also use the blast gates that are used for dust collection with our ferrets too. We have put our litter boxes in cabinets outside the cages. Then we connected tubes to blast gates which are fixed on the side of cabinet. (When you see a picture of a blast gate you can see how it works.) When the litter pans need scooped we slide the door to the blast gate shut so the ferrets can't come thru, scoop, then slide the door back open. It is a huge time saver and makes scooping much easier. Our ferrets like to "help" with the scooping. This way we can scoop uninterrupted and have more time to play with them. With all the different connectors they sell for these tubes you could put together a very elaborate tunnel system for ferrets to play in. I would recommend them to anyone with ferrets. They do cost more but will last a lot longer. Nancy [Posted in FML issue 5331]
