PHILADELPHIA: A rare tiger gave birth to three cubs at the Philadelphia Zoo, according to a media report.
A keeper spotted the first cub in the cage Friday and soon saw three nursing successfully. Zoo officials do not know the genders or exact weights of the newborns, but they are estimated to be about 2 pounds (910 grams), The Philadelphia Inquirer reported.
The zoo announced last month that Kira, an Amur tiger, was pregnant after mating with a male named Dimitri. There are about 144 Amur tigers captive in North America, and only about 400 left in the wild along the Russian-Chinese border.
Experts caution that a lot can happen in the early life of a tiger cub.
Last year, in Pittsburgh, the runt of a three-cub litter died at five weeks because it had an enlarged heart and a small stomach.
Kira has had 10 cubs in previous litters, but one was stillborn and another died shortly after birth.
