One day he’ll grow up to be a fearsome predator. But for now, Siku the polar bear is quite content to enjoy life as a cosseted cub.

The tiny bear is being hand-reared at a wildlife park after his mother was unable to produce enough milk to feed him.

Footage of the month-old cub sleeping, stretching and wriggling in delight as he gets a rub down from one of his carers has won him thousands of fans online.
