I agree!  These things are GREAT!!  I have been using mine for about 2
years, well, actually the ferrets have been using them for about 2 years!
They are indestructible and the ferrets seem to love the noise they make
when they run through them!  You can cut them for whatever size constraints
you have, I got a 12 foot tube for about $2.94.  I think they are much
safer than the clear plastic ones.  There is nothing for them to chew apart
or through.  The only downside is you can't see them in it, but they make
plenty of noise so I always know when mine are playing in them.  My little
demons, uh, I mean, darlings, like to ambush me as well as each other and
not being able to see each other in them makes it more fun for them to do
this.  Check it out, it really is a great deal!
