The yarn balls made of robust solid wood are designed in multiple colors with saliva-resistant paints and are ready for playtime with the gray kitten. The goal is to place the wooden cylinders on the cat in such a way that it remains balanced. The included color die indicates which color should be placed next on the balancing seesaw. The large yarn balls made of colorful solid wood are well-suited for small fingers and help train fine motor skills. A great fun for all small and big cat lovers and patience game fans.
