my mottie ,even though she has a cold , really tough one at that, she enjoys getting new toys like the one in the picture, she has inter reacted with it only a bit but it's due to her cold ,the toy is just the right size for her, she loves the tail on it and she likes swatting at it to make it roll across the floor so she can race after it. it even moves on the carpet with ease, it's a low cut carpet but it rolls right along with here playfulness .
