Prairie Dog Lover's Burrow

My male has outgrown his exercise wheel attached to the side of his cage.  It is 12 inches in diameter and we need something larger,  Any suggestions?  Thanks!

I found a 15 inch wheel that is great in my cage. It cost about 45.00, but the PD's love it.

I believe it was from Brisky pets...but I am not sure.

here it is for 35.00, it is the one I bought and my prairie's love it

If you have more than one prairie dog being housed in one enclosure, this is the wheel I recommend:

Although most other 15" wheels are the correct size, and metal wheels are the most durable, those that are open with no support bar are the safest for use with prairie dogs.
