Ok I am curious what this behavior means and if I should be tolerating it or putting an end to it! One of my cats sometimes likes to lick fingers and your face and well whatever other bare skin he can haha! He sometimes though will take your fingers in his mouth and well kinda lick/mouth them. He is definately not biting and judging by when he does it it seems to be an affection thing. But I am a cat newbie so wondering..is this a behavior that could escalate to real biting/nibbling or should I continue to not worry about it? Also why does he do this? I should note the other cat licks sometimes but no mouthing.
