Cat Scratch Fever

Olie has an odd nervous habit. Has for a while, but lately it has been escalating. He scratches his head whenever he gets nervous or uncomfortable, and in spite of the fact that he can barely even reach the top of his head. Early on we learned to keep his nails short, but still he scratches and scratches, sometimes until he starts to bleed. He's now got all kinds of scars from this bad habit. I've spoken to him about it explaining that masochism really is not allowed in our household, but my discouragement appears to be falling on deaf ears. Apparently, this nervous twitch of his isn't all that uncommon since baby stores sell infant mittens to resolve this very issue. But, as with most of Olie's other parts, he just doesn't have infant hands. Anybody have an extra pair of lightweight toddler mittens leftover from last fall?
