this one is fun for the critters, they love the turning and trying to catch, Very entertaining for the rattys and me...

Pros: wheels are number 1 for the rattys

Cons: ,,

I bought a lavender senior wodent wheel for the girls. You can even stick little sandpaper inserts in there to keep their pedicures up to date. Too bad my girls aren't wheel lovers!

Pros: It's safe, quiet, easy to clean!

Cons: My rats don't give a rats pa-tootey about it!

i had to rearrange the cage and take out the wheel that came with the cage. This one is nice and the hamster likes to use it.

Pros: quiet

Cons: little large for cage

My pet gerbil once broke his tail in the running wheel. It did heal but was always crooked.

Pros: Might be good for a hamster with no tail

Cons: Not good for a gerbil with a long tail
