In a used bookstore today, an old copy of The Lives & Times of Archy and Mehitabel began to call my name. I had flashbacks to my high school days when I first met them.
There is now a Don Marquis website, of course, which has a nifty description of the protagonists:
THEY ARE THE MOST UNLIKELY OF FRIENDS: Archy is a cockroach with the soul of a poet, and Mehitabel is an alley cat with a celebrated past — she claims she was Cleopatra in a previous life. Together, cockroach and cat are the foundation of one of the most engaging collections of light poetry to come out of the twentieth century.
