Awww, how cute! At least it's getting used.
Willie seems scared of the catnip mice I bought for him - *sigh*. However, Mio left a project he did in school, representing the life cycle of the butterfly, on the floor yesterday. It had little pink cotton balls that represented the eggs. Willie got one off and had a GREAT time chasing it. The funniest thing was that when it rolled somewhere he couldn't get at it good with his paw, he carefully picked it up with his mouth and relocated it. As he's generally very sedentary, that was a sight to see!
