MIAMI – A Sumatran tiger cub who was the first and only of its kind born at Zoo Miami celebrated his first birthday on Thursday.
Satu was born last November to first-time mother Leeloo and first-time father Berani.
Satu was the only cub in the litter, and zoo staff had to supplement his feedings to help him survive in his initial months of life.
Zoo Miami spokesman Ron Magill said Satu has since thrived at the zoo and is now regularly on exhibit with his mother.
"He had a couple of medical issues (and) he got over those hurdles, so that first year of life, it's really the most treacherous for these animals," Magill said.
Satu weighed about 2 pounds at birth and now weighs well over 100 pounds, and he isn't fully grown yet.
On Thursday, he got to enjoy a special birthday cake topped with meat.
Magill said there are believed to be fewer than 500 Sumatran tigers left in the wild. The Sumatran tiger is native to forested areas on the island of Sumatra in Indonesia.
The tigers' habitat is threatened by palm oil plantations and poaching.
Magill said the Sumatran tiger is the smallest subspecies of tiger. Males typically grow to be about 300 pounds and females grow to be about 200 pounds.
