New London Zoo triplet tiger cubs in 'rude health'

The cubs were born to five-year-old Sumatran tigress Melati in February

Six months after a rare tiger cub died, London Zoo's new triplet cubs have been given a clean bill of health.

The Sumatran tigers born in February were examined, sexed, vaccinated and micro-chipped.

They were born in February to five-year-old Sumatran tigress Melati whose last cub - the first tiger to be born at London Zoo in 17 years - was found drowned aged four weeks.

Nic Masters, head vet at London Zoo, said they were in "rude health".

There are estimated to be only 300 individual wild Sumatran tigers in the world

The triplets, born after a 106-day gestation, were found to be two males and a female.

A critically endangered species, there are estimated to be only 300 individual wild Sumatran tigers in the world.

The last cub died in a pool inside its mother's enclosure in October last year.

The cubs were vaccinated and micro-chipped by a team of two keepers, a vet and a veterinary nurse
