Wheels

Wheels are a great addition to your chinchillas cage.  The main thing is to get the right wheel that is safe for your chin. 

This picture is a 15" chin spin behind a 12" silent spinner.  I would never recommend using a plastic wheel as they will get chewed and are way too small. 

There are only 3 wheels I would recommend, The Chin Spin by Quality Cage, The Flying Saucer  or the Silver Surfer by Chinchillas.com 

Small wheels will harm a chins spine over time. It's best to buy one that is safe and will last a lifetime.
