YES!!! My family's cat, who passed away a few years ago, was banned from the bedroom. We discovered that she loved to "groom" her humans while they slept. It was nasty. Imagine waking up at 3am to find your cat licking and trying to untangle your messy bed hair. There's nothing like a head full of cat saliva and ouch, she was not the gentlist stylist I've ever had. She was my favorite of the cats we've had so far, but the hair thing was a bit weird.
