Best toy ever for a smart cat. My cat Milo gets bored and looks at me like I must be kidding if I play with the fish on the string. But put this cute little chirping bird in a poster tube and he's happy for hours. He loves the challenge of getting the bird out of the tube. It's just over twice the length of his paw so it takes some maneuvering for him to catch it. Each time he bats the tube, it causes the bird to chirp and keeps his interest. The only thing I recommend is putting the bird in a hiding spot at night. It's not a pleasant noise to wake up to.
