If a black cat follows you home at midnight… “Poe” is a pretty safe call for a name. (It helps if you’re a big Poe fan, too, like I am.)
He loves to roll around, so it’s also short for “roly-poly.”
(His initial working title was Bradbury, in honor of Ray, but it just didn’t work. Didn’t suit him.)
I once knew of a guy who named his cat, “‘Ted.” It was short for “Shithead”.
