I have a kitten that is about five months old now and he often crawls on my chest and licks my face. It's annoying, but I let him do it one day. Let me just clarify that the results from the cat licking my face were incredible. My skin was an extremely smooth canvas and my blackheads on my nose were almost unnoticable. Maybe a cat's tongue is a miracle exfoliater? Cats use their own tongues to clean any impurities on themselves, so why wouldn't it work for scrubbing and deep-cleansing the pores on your face? It may sound like a nasty idea, but why not? You can always wash your face anyways. I say we give cat's and cat lovers a + for this advantage.
