Cute polar bear cub the size of a guinea pig snuggles up with mum

A polar bear cub the size of a guinea pig looks to be dreaming of a white Christmas in adorable secret footage captured yesterday (December 13), snuggled up with their mum.

The 14-day-old cub, kept at the Berlin zoo, spends most of the day snuggled up to mum in a nesting cave that even zookeepers aren't allowed in.

But new camera technology at the Berlin Zoo means everyone can follow the newborn's development in the cosy den from afar.

The cub's eyes and ears will open when it is around 30-days-old but for it now relies on mum Tonja to keep warm and safe.
