Marshall Pet Products Super Thru-Way - 15-Foot Interactive Tunnel for Ferrets and Small Pets, Durable and Flexible Design, Encourages Play and Exploration

I just got this a few days ago from Amazon, and already it's turned into my ferret's favorite toy. Nothing else (save for a plastic water bottle that he likes more than his expensive toys, lol) has held his attention for as long as this, and he keeps going back for more! He especially finds it fun if you sit on the floor and twist it all around yourself, up over your shoulders and under your legs, so that he gets to climb, slide and twist to get through the whole thing. He also finds it likes me to run the tube through a dark cardboard box, or move the ends while he's in the middle so that it comes out in a new place every time. At twenty feet this tube stretches out well, much better than the other eight foot tubes that you can find in stores, and the clear plastic is nice because it allows you to see your ferret and vice-versa much better. As one of the other reviews said, though, he does like to chew the ends; since I supervise him during play time, this hasn't been a problem, but I might take their advice and cover the edges with some duct tape. And even though he tries to "dig" his way out of the middle of the tube from inside, the plastic seems to be sturdy and is holding very well. The tube also smelled very strongly of plastic when it first arrived, but it aired out well within about a day and no longer smells like anything. Every ferret definitely needs one of these! =)

Bought 3 times, it’s that good. Great quality. Only downside is that it smells a little chemically when you put your nose in the tube, but you can easily ventilate it out.

My ferret loved this! Its a favorite

It's flexible too! It's bendable wire wrapped in plastic, but thick enough that my ferrets claws don't rip it. Ferret was confused at first, didn't like the noise at first. Or the smell. Did not like the fresh plastic smell, neither did I though. She didn't like it at first so I made it her exit/entrance for her cage to the rest of her room. She uses it freely now and when I put it away keeping her in the cage (I can clean without her being scared or hurt) she looks for the tunnel and throws a fit when she can't find it.

The ferrets absolutely love this thing. They spend half their time in it when they’re out of their cage. They’re hysterical to watch too. Only not so great thing is it doesn’t stay expanded! You have to wedge it or tie it. I managed to rig a contraption to get it to stay but it’s still quite obnoxious.

The ferrets loved it, but they eventually tore a hole in it. Lasted about a week. It still a must have. Even with the hole, they still play with it.

My ferret loves this more than she loves me.

Used once. Put back into the box. Opened for second use and the product tore. It doesn't stay stretched out. Ferrets do enjoy it. I do not reccomend this product.
