CUB CHECK-UP: Two Sumatran tiger cubs received their first check-up and vaccinations at a zoo in Berlin, Germany, on Thursday (4/25). The two-month-old babies were also seen exploring their enclosure while their mom Mayang watched from nearby.

Sumatran tigers are one of the most endangered subspecies in the world, with only around 400 to 600 in the wild, according to the Berlin Zoo.
