Man.. Zeke licks his feet at night! Its so annoying.. not sure why.. there's nothing abnormal about them. We just firmly say 'Zeke." and he stops.. lol. But if we just let him go.. he'll do it forever... I'd definitely agree with taz_zoee and say its a habit they've formed. We just get after him enough and he stops for the next couple of days usually.. not sure about a permanent fix.. a spray might work though.. Kinda like that stuff people use to stop biting their nails, I guess.
