borderp, if you're chins are using a 12" please remove it before they have permenant spinal injury... a wheel must be atleast 15" to prevent spine injury. One thing I like about the flying saucers is that people don't run on curved treadmills, yet they expect their animals to do so. The bigger surface the better it is for them to fully extend.
I went to the local Micheals store this evening looking for a 16x4 pan as someone here suggested. No luck. I found a 12x4 and 14x2 and a 16x2 pan. Very sturdy for our little guys, but nothing in the size I'm looking for.
This brings me to a question... I'm not sure a 16" wheel will fit our cage. I hear you loud and clear about the 12" plastic one we currently have. I told my wife I want to pull it out, but it'll have to wait until I have time this weekend to take thier cage apart. I'll need to find a way to keep it from turning inthe mean time.
I think I can find a 14x4", thats 2" bigger as well as deeper than I currently have and it will be without a center rod over thier backs. Or were you refering to the diameter circumference causes them to arch thier backs?
I just measured my cage, allowing for minimal flex of the wire cage do to the wheel while in use, I do not believe I have room for a 16" wheel. Looks like a 14" would fit comfortably . 15" would be pushing it. :impatient:
