Pics would be great

has she had any traumatic injuries...a fall or something??

How Old is she??

What kind of enclosure is she in (include bedding, furniture, enrichment items)

Has she been on any medications lately? (I figure you probably just euthanize sick animals in your colony, but wanted to check anyway)

Any previous history of other animals in your colony having weird behaviors: running in circles, wobbly gait, etc??
