This is fun for the kids to create a tunnel for the small critters. Teaches them responsibility, taking care of and making sure the pet is having fun.

Pros: colorful, connect, fun

Cons: none

My gerbils live in three cages that are connected by these tubes. They have always enjoyed them and I highly recommend using them for your pet.

Pros: Great for connecting multiple cages

Cons: can be difficult to clean

I had cages and these tunnels when I had a hamster. They were a lot of fun and it was cool to watch my fluffball hamster go up and down. The ones that stand vertically off the top of the cage though and end in a little spaceship like thing, don't always stay up well on their own

Pros: fun

Cons: somtimes the vertical tubes off the top of the cage don't stand up

Our hamsters love these tunnels. They go in them all the time and just hang out. The only bad thing about them is cleaning them.

Pros: fun for the hamsters, place to hide

Cons: hard to clean

it is very good for young hamsters, but old ones just get lost inside

Pros: colorful, resorceful, sterdy

Cons: hard to take apart
