The Berlin Zoo is celebrating the first birth of Rusty-Spotted Cats in its 168-year history. Rusty-Spotted Cats are the world's smallest wild cats, weighing only 2.0 to 3.5 lb (0.9 to 1.6 kg) as adults.

The two kittens were born on August 5, and have only recently begun to leave their den to explore their exhibit. Playful, clumsy, and a little awkward, the two female youngsters are a delight to zoo guests. At birth, kittens typically weigh just 2.0-2.7 ounces (60-77 g).
