Frequently Asked Questions
What happens if a hamster wheel is too small?
A wheel that is too small forces the hamster to arch its back unnaturally while running, which can cause permanent spinal damage, pain, and reluctance to exercise. Always err on the side of a larger wheel.
Should I get a wire mesh or solid wheel?
Always choose a solid-surface wheel. Wire mesh or rungs can trap tiny feet and toes, causing injuries known as 'bumblefoot.' Solid plastic or metal wheels with a flat running surface are safest.
