ZooZoo and HooHoo love to run in their tunnel! We have one of the 20 foot flex extensions and they just think it's the greatest invention since sliced bread! LOL I love the bright colors and the ability to add more extensions!! With this tunnel, you're only limited by your imagination and your wallet! LOL My only complaint is the price, but I'm a nifty thrifty, so it probably doesn't bother most. However, I bought it anyway, and I'm pleased with my decision to purchase!!:)

Pros: Ability to expand, easy to snap together, fun!

Cons: A little pricey...$20.00 for one flex extension

we have several of these in Phipps' cage. he loves climbing around and doubling back in them between the main levels of his cage. we also have a few elbows attached to a shelf with an opening so that he can get down from one level to the next. great product: functional and fun to play in.

Pros: they can be connected in so many combinations

Cons: they can be expensive in pet stores

This is a great item for small pets. It's somewhat translucent so you can see them while they are inside. It's completely washable so you can keep it clean. I would recommend these.

Pros: guinea pigs love to tunnel

Cons: can be chewed

tunnels... you can attach to more tunnels... so your little animal can play in the tunnel longer.

Pros: none

Cons: none
