Our tiger cubs are 3 weeks old, and this morning they got their first veterinary exam—and passed with roaring colors. Veterinarians determined that the 2 cubs are a male and a female. The male cub weighs a little more than 8 pounds and the female weighs 7.5 pounds. During the exam the cubs received transponder microchips, and veterinarians collected blood and fecal samples from them. Veterinarians and keepers report the cubs are healthy, plump and growing quickly.

The cubs will not be on exhibit for several months until they have completed a series of four additional health exams, during which they will receive all necessary vaccinations.
