Ferretrail bubble wave fun-noels maze includes both a tube and elbow to create tunnels of fun for ferrets, guinea pigs, pet rats, chinchillas and other furry friends. Ferretrail fun-noels can be connected to each other creating a colorful peek-a-boo playground system of tubes, elbows and tees. The ferretrail system was designed to provide many hours of stimulation and fun for pets through natural exercise. Fun-noels also provide pets with a unique network of hiding places and tunnels to explore.
