Title: EXTREMELY dangerous for guinea pigs
Review: Guinea pigs should never use wheels or those plastic run around balls, they are EXTREMELY bad for their spines and can cause extreme plysical dammage. Guinea pigs have very sensitive spines and any activity that cause their spine to bend should be avoided.Do NOT buy this product, (or any prouct that causes your pig to bend their body in any way) it will harm your guinea pig.I know this from long time guinea pig owner-ship and from working at an animal hospital.
