Uhmmm... Winnie... I am sorry to tell you this, but I've learned the hard way that you can't always blame it on your big brother. Maybe there was another kitty who came in from outside, attacked the cat toy, and left? I am quite sure Groucho and his team will get to the bottom of it, though.

P.S., you are very beautiful! And Angel, you're just a perfect circle of kitty!
