The only one of my furbabies who "grabs" is Winchester. He'll do it as you're walking by, which in most cases you can "dodge" his grab. But if you happen to get up in the middle of the night to go to the bathroom and you don't see him, he'll usually get a good shot in!
He also has a habit of grabbing your arm or hand when you're petting him, and won't let go till he gets one of his "love bites" on you. Ouch!
Oh man. If we don't do exactly what Jeckale wants exactly when he wants it, He makes sure we pay. He'll wait until we walk by, grab our leg, then run. It's actually kinda funny. But sometimes it hurts haha
