After a London Zoo awareness event called Streak for Tigers took place this past August, the good will of a dozen or so naked runners has apparently worked wonders for preservation. Last month, Melati, a rare Sumatran tiger at the ZSL London Zoo, gave birth to three cubs. There are less than 300 Sumatran tigers left on Earth.

The birth and subsequent babyhood of the young cubs was captured by the London Zoo's Cub Cam and the footage is predictably adorable. Zookeepers haven't yet interfered with the new family, so the sexes of the infants are unknown, but one has been nicknamed "Trouble."
