Abbey licks us (and everyone else she can get her tongue on) all the time. She will lick my brother for an hour--he lays down on the couch and just laughs while she licks his face. She curls up in bed with us and licks til we stop her, because we want to sleep.
Kito on the other hand, is a snob. He will give kisses sometimes, like when we come home, but otherwise, only if we've just eaten something he likes the smell of.
