Ethical Pet Kitty Fun Tubes Cat Toys (3-Pack) – Three lightweight, springy mesh tubes in vibrant colors that drive cats wild with their erratic bounce and roll. Each flexible tube is like a little mesh tunnel infused with a bit of catnip, and cats love to bite, paw, and fling them across the floor. Their open, bouncy design and fun texture make them easy to bat around, providing tons of interactive chasing exercise and mental stimulation for your feline friend.
