At first I thought he was doing what my Mellie (aka Caramel) loves to do - eat a few strands of my spaghettti. Then I realized it is probably the cord to a blind. Please be careful - my cat Riley almost choked playing with the cord from my blinds in the kitchen - I had just opened them and so the cord was hanging lower than usual and I hadn't wrapped it around the curtain tie back hook yet. They like to play with it, especially when it's dangling, but it can end up in their mouths with their abrasive tongues, and they can't get it out and they just keep swallowing (many cats have had severe or fatal injuries from wool and string also). Wouldn't want anything to happen to Mr. Murphy!
