In Harry Potter, werewolves are people that turn into wolves at full moon, and go around biting people, turning them into werewolves. Examples include Remus Lupin and Fenrir Greyback, both of which are humans until the moon changes.
Tom Riddle claims that Hagrid kept werewolf cubs under his bed:
big, blundering Hagrid, in trouble every other week, trying to raise werewolf cubs under his bed, sneaking off to the Forbidden Forest to wrestle trolls...
Chamber of Secrets, Chapter 16
Surely a werewolf cub is a baby that turns into a werewolf cub at full moon.
Am I correct in this? Are werewolf cubs actually human infants with a weird reaction to full moons, or something else? Or is Tom Riddle simply trying to frame another 'bad' thing on him? (which seems unlikely, why would he continue the lie to Harry, when it means nothing?) If they are human, how did he get away with it, and what was the motivation? (knowing his affiliation with more exotic beasts)
