We discussed the fact that both human girls and human boys have nipples, just two of each. Cats clearly have more though. "How many nipples does a cat have," we wondered. And do boy cats have the same number as girl cats? Fortunately a cat was nearby.
I learned something that night. This is good, because a late-night rambley conversation is worthless if nothing is learned.
I learned that cats hate to have their nipples counted.
