when kittens and cats lick their noses/whiskers. This could be for a variety of reasons, such as food on the kitten or cat's face. And some kittens and cats just mlem mysteriously. I don't think that it should be called a mlem when dogs lick their noses/whiskers, but some people would consider that a mlem.
the kitten was hungry, so he mlem'd to get the fish off his whiskers.
