We've heard of stretch greetings, but do you also get scratch greetings? Every time my husband or I get home, Murphy greets us and immediately finds something to scratch -- a leg of the couch, the wall, or most often, the tops of our shoes. Is there something about scratching that says, "I'm glad you're home"? Or maybe it's an anxiety type reaction, like "Uh-oh, incoming. Better scratch something to prove this place is mine."
