NOU (pronounced like 'noo' in noodles) is a play object designed for both your pet and you. To make it fun, the object invites you to be creative too in making various shapes. NOU can be a pretzel, a boating knot, a tossing ball or a tug of war rope. Works like an enrichment toy, treats can be hidden in the knots and rewarded when your pet successfully unknots them. If one NOU is too easy for the pet, level up and make more complicated shapes with two or three NOU!
