Philadelphia Zoo's female Black-footed Cat Aza gave birth to a litter of kittens on April 8, 2014: the first Black-footed Cats ever to be born at the Philadelphia Zoo! Their names are Drogon, Rhaegal, and Viserion. Drogon and Viserion are male and Rhaegal is female.

Before making their debut, the kittens underwent a routine wellness check to make sure they’re healthy. In addition to weighing and sexing them, veterinarians completed full physical examinations of each kitten. They also gave the kittens dye marks so the keepers can tell them apart from a distance. Philly Zoo also baby-proofed the kittens' exhibit ahead of the big debut. They lowered the water level in the exhibit and added climbing structures so they could enter and exit their pool with ease, and before entering their exhibit, they practiced with different amounts of water in their indoor bedroom. They also added another feeding dish so Aza could eat separately from her kittens, and they placed the kennel they had been sleeping in inside the exhibit so they would have some familiar scents. A keeper is present to monitor them throughout the day to make sure they're maneuvering through their habitat well, but as you can see in these photos, they are feeling quite at home already.

Just last week, the kittens received another checkup, which included vaccinations, reapplication of dye marks and weighing. Their weights now range from 631 to 757 grams (from a little more than 22 oz. to a little less than 27). All three babies are in great health.

These small but mighty cats are terrestrial and crepuscular (active at dusk and dawn). They are not great climbers, but are skilled diggers when looking for insects or creating birthing dens. They have been observed to have several hunting styles that include: fast hunting (running through and over vegetation, flushing out prey), slow hunting (slow, stalking movements- which indicates they are low to the ground in an almost serpentine motion), and finally "sit and wait" hunting (motionless vigilance at a rodent burrow waiting for an animal to come out of their den). All of these methods have proven successful for this cat. On the 2011 IUCN Red List of Threatened Species, the Black-footed Cat is listed as Vulnerable.
