Yes, we all know that cats are fanatical groomers (that is, lickers) of themselves, but every cat owner also knows that a cat will also groom his owner, and other cats as well.
Naturally there are technical terms to employ here: autogrooming refers (of course) to the cat’s grooming of himself, while allogrooming refers to licking other cats or humans. The cat spends less time and attention on you than on himself for the obvious reason: he assumes (correctly or not) that you are responsible for keeping yourself clean.
