Springing it

I'm sitting in a recliner with my feet up, reading a friend's book. The window to my left is open, and Mac is poised at the sill, his shoulder muscles tight and his head shaking while he makes his squeaky noise that says he's targeting something bird-like. Under the cabinet to my right are noises indicating the turtles are, um, enjoying the fact that it's spring. Yes, it's a lovely spring day.
