Walbest 10Pcs 1 42 Cat Toy Ball with Bell Pet Toy Cat Bell Ball Cat Toy with Bell Cat Jingle Balls for Cats Kitten Plastic Cat Toys Jingle Balls Pounce Rattle Ball Toys Random Color

the 3 cats love these balls with bells inside. I hear them playing with them during the night too LOL. I do play with all the cats with the balls only at least once a day. They just go kooky over these. We have cat toys all over the house but eventually the balls with bells inside are the focus.......I think it is because they are heavy enough to be rolled a very long way.....from one end of the house to the other. I even have put one in a few stuffed toys. The balls are hard plastic and that makes the bell inside bang around more and makes more noise. better than the other balls with bells inside.
