This is the adorable moment a Sumatran tiger cub takes its first steps outside at a London Zoo.

Footage taken by zookeepers at ZSL London Zoo yesterday (Wednesday, 12 January) shows the critically endangered cub taking its first wobbly steps outdoors its enclosure – a month after its December birth.

ZSL London Zoo tiger keeper Kathryn Sanders said: “The cub has so far mostly stayed tucked up with Gaysha in their cosy behind-the-scenes cubbing den, but with such lovely weather yesterday it’s clear she decided it was time for her little one to take its first steps in the outside world.”

After carrying the tiny tot outside in the afternoon sun, mum Gaysha set the cub down safely in their heated outdoor shelter before taking the opportunity to stretch her legs.

London Zoo keepers - who have been keeping a close eye on the family via CCTV - captured the adorable moment the determined youngster followed in mum’s footsteps, tumbling onto the soft grass along the way.

Kate added: “We were all holding our breath with excitement as the cub tottered around, using all its strength to clamber after mum – it was incredible to watch the youngster find its ‘tiger feet’ for the first time.”

Keepers will discover if the as-yet unnamed cub is male or female at its first health check in a few weeks’ time – in the meantime, lucky visitors to ZSL London Zoo might spot the cub as it ventures out more and more over the coming weeks.
