Meet the mid-size "NOU", also known as "NOUNOU". This versatile play object is made of nylon knot fabric with crinkle papers inside, ideal for pups who love the sound of us crushing up papers and plastic bottles. Stimulate curious minds with different knots and shapes daily to entertain your pups and kitties for hours! Stuff some of your pet's favourite treats within the knots and watch them work for their reward.
