My Microsoft Sculpt Ergonomic Mouse's scroll wheel has been acting weird lately. I have a feeling it is now full of cat fur and I wish to clean it but I can't figure out how to open this rodent! Couldn't find any teardown videos or tutorials of it. I couldn't find any screws, at least not anywhere easily accessible. The stickers showing the battery directions - which was the most likeliest place for screws - didn't have any. I'm a little afraid of pulling the rubber covers off the mouse if there's nothing under it anyway. Maybe someone can point me to the right direction?
