    It doesn't have to be, but often is:

    From our dictionary ... lap
    vb (laps, lapping, lapped)
    1 (of small waves) to wash against (a shore, boat, etc), usually with light splashing sounds
    2 (often followed by up) (esp of animals) to scoop (a liquid) into the mouth with the tongue

    No, at is fine.

    Lapping up indicates consuming, usually eagerly; the up emphasises "in order to do the complete action."

    With lapping at the at is a simple collocated preposition, as in "He was playing at chess." The word has little or no meaning and can be omitted.
