Bests & Worsts Reviews from Amazon

For those of you who mention that your guinea pigs wriggle around in these and can't get out - they're wriggling because guinea pigs' spines are not meant to bend in the way a harness requires them to walk, and they're in discomfort or pain. Make a large, safe enclosure in which your guinea pig can safely exercise. Do not use a harness. If you want a pet to walk with a harness, get a dog.
