Remarkable footage of our Sumatran tiger giving birth!
Sumatran tigers Fabi and Kirana wake from their slumber in their den at Chester Zoo as mum Kirana gives birth to the first of two cubs.
With numbers in the wild believed to be as few as just 300-400, Sumatran tigers are classed by conservationists as critically endangered. The arrival of these two latest cubs is therefore vital to the ongoing survival of the species.
