Ethical Pet Sponge Soccer Balls Cat Toys (4-Pack) – Four soft foam soccer-ball toys (approx. 1.5–2 inches in diameter) in pastel colors that cats can easily bat and carry. These sponge balls are ultra-lightweight and roll smoothly, but also have a bit of bounce if tossed, making them great for games of feline “soccer.” Because they’re made of squishable foam, they’re quiet during play (no loud bouncing or bell noises), and they won’t damage furniture perfect for indoor cats to chase and paw at all day.
