Ballmie Cat Toys Baby Bell Ball is our own brand design, from original cloth pattern design to final packaging by our designer team. The ball size is 1.4-1.9 inch diameter which is good for adult cat to crinkle and chew easily in mouth. We do research with our designers on our cat behaviour and preferences, and we try to integrate cat toys into our home decoration. As our cat may chew the ball in mouth safety, we finally selected the soft comfortable velvet cloth, which is made by Eco-printing technique at Human Baby Cloth Grading. If your cats love to chew balls, these balls are good for them. Hard Bell is included in each ball. Random color of 6 balls are selected in each box.
