Cat Toy, Felted Wool Balls. Handmade From Ecological Wool Made By Kivikis. Rainbow colored, super soft, 100% wool ball toys. Your pets and kids will love this handmade felted wool ball toy! Give your sweet little ones safe, natural wool toys to play with. I wind the wool by hand and use West Australian wool tops which I felt using organic soap nuts. You can even use them around the home as home decor. Small dogs may enjoy it too!
