This is something I believe that all ferret owners should have. I have four ferrets and they all love it! It is great to use when playing with your ferrets and the ferrets will play in it by themselves or with their playmates without you. They absolutely love it and I have never met a ferret that does not like it. This is the best purchase, next to my ferrets and their large cage, that I have ever made for my pets. They can be hard to find but if you look on the internet you should be able to find one and they are not that expensive. I suggest the long clear white ones, rather than the colored ones, because they are longer and cheaper.
You can keep the tube straight or rearrange it every once in awhile into different shapes. My ferrets love to chase one another throught them and to crawl into it and have us dump them out of it.
You need to get it!

Pros: They LOVE it!

Cons: None!

I have four ferrets and thy absolutely love this tunnel. It's flexible so you can twist it around things (or yourself) and give your ferrets something different to run thru every day. It's great because it's see-thru. We have black tubes and could never see what they did while they were inside. It's so funny to see them stretch and yawn and pull themselves thru this tunnel. This was a great investment for our fuzzies!

Pros: lots of fun, easy to set up, very flexible

Cons: -

My ferrets had fun with this but after a while it got dirty (despite bathing the ferrets every other week) and I had to throw it away. Also as they got older, the less fun they had with it.

Pros: Ferrets like it for a while

Cons: Gets very dirty
