ANIPAL Piper The Platypus Collar (Made from recycled plastic) LPiper the Platypus Collar and Leash recognises an iconic species of Australia. Our one and only aquatic monotreme, Piper is an exceptional swimmer. He has a bill like a duck, a tail like a beaver and is quite a spectacle too see, if you can spot him. Piper is shy and, sadly, his species are susceptible to pollution in the waterways. Let?? clean up our act for Piper! All our products are made from recycled plastic bottles and brass hardware.
