Stacks are fun cat toys made from 100% Merino wool felt in festive holiday colors. Each toy is made with odd shaped pieces of felt, which give it an unusual shape that will bounce unpredictably across the floor. The felt pieces are held together with a black bungee cord. Kitty will love the texture and you'll love the fun colors! Each toy measures approximately 2" x 2.5". Handmade in the USA.
