Jaguar Cubs / San Diego Zoo

One of two Jaguar cubs born at the San Diego Zoo on 27 April takes its turn on the scale. The 12-day-old cub, which weighs 1.9kg, is still too young to get on and off the scale on its own. The two unnamed siblings will remain in the den for a couple of months until they are able to walk outdoors on their own. Keepers have yet to determine the sex of the cubs. The pair are the first Jaguars born at the San Diego Zoo since 1989 — via ZooBorns
