LONDON, March 13 (UPI) -- The London Zoo announced the Sumatran tiger mother whose cub drowned last year has given birth to triplets.
The zoo announced Melati, a 5-year-old Sumatran tiger, gave birth Monday morning to three cubs whose genders have not yet been identified, the Guardian reported Thursday.
"We couldn't be more delighted with our new arrivals, and with how Melati is responding to her three cubs. ... We've even been able to observe key milestones like their eyes opening and their tentative first steps," zookeeper Teague Stubbington said. "While we still don't know whether they're boys or girls, we're starting to see their personalities develop. We've nicknamed one Trouble, as it's much bolder than the others -- it was the first to start exploring its den and we've spotted it waking up its siblings when they fall asleep."
Sumatran tigers are classified as critically endangered, with an estimated population in the wild as low as 300.
