First, a friend who was moving ended up leaving most of his books with me. One of the books is "The Life and Times of St. Francis", and both Charles and Allie seem to know that St. Francis is the patron saint of animals, because each of them at different times today took a nap lying on top of it.
Second, the dish that Charles has his head in contained catnip. Allie was actually roughly where he was (there was another dish on the floor with Charles' catnip), but Charles chased her away to take her catnip. I can only assume that the wild party held by the potsmokers across the hall influenced him to behave this way. I'm glad to see that Allie did come back to sleep on the arm of the couch.
