Add on to your ferret's habitat and ferret cage with Ferplast ferret play tubes and tunnels which are suitable for rats as well as ferrets. This ferret tube is curved and measures 9.8 inches in length and 4.1-inches in diameter. These play tubes are easy to suspend from the cage by using the two clipped chains. Although this was specifically created for the Ferplast Ferret Tower, it should also work on most other ferret cage's manufactured with mesh wire. The ferret tube can be suspended on its own, or can be joined to other Ferplast play tubes to create a longer tunnel..
