Thanks to Kelly, we have not only this photo, but the story behind it:
“Pogo waking up after a refreshing (?) nap on one my hardcovered Agatha Christie books. He is trying to improve his “little grey cells” by sleep reading some Hercule Poirot mysteries. (And his little grey cells can definitely use some improvement!)”
Oh, well, we love Pogo even if he doesn’t increase his brain power.
