This is the adorable moment two rare Sumatran tiger cubs emerged from their den for the first time for some playful 'rough and tumble' after being born at Chester Zoo.
Twins Alif and Raya were born at the attraction back in January but have only just started to venture out and explore the outside world.
Zookeepers caught on camera the cubs taking their first steps outdoors before enjoying some playtime under the watchful eye of proud mum Kasarna.
