Collapsible Pet Tunnel, 2 PCS Hamster Fun Plastic Tunnels, Foldable Hideaway Exercising Training Tube Toys for Dwarf Hamster, Guinea Pig, Gerbil, Mouse, Rat and Ferrets

Not good for Guinea pigs, too small.

Good product but bought it for my birds since they like hiding in things but they are terrified of it lol

My ferret can fit in this but its on the small side. Not very long either.

My ferrets love these!

Really durable and my ferrets love them. But 2 of the 4 I ordered came dirty with like dust or some kind of dirt, probably from the factory they were made in.
