Pictures show Edinburgh Zoo's three adorable lion cubs exploring their home with mum Roberta

They're growing so fast!

Three five-month-old Asiatic lion cubs have been spotted enjoying some winter sunshine with mum Roberta at the Royal Zoological Society of Scotland’s Edinburgh Zoo.

Following a public poll in November last year in conjunction with the Evening News, the wildlife conservation charity named the youngsters Mitaali, Keshari and Kushanu in tribute to the Gir forest in western India where the endangered species is found.

The family are starting to spend more time outside as the cubs continue to grow and become more confident.

The three cubs were born at Edinburgh Zoo on 15 August 2019.

The Asiatic lion differs from the African lion in several ways. Asian lions are generally smaller than their African cousins, and the males do not develop such a substantial mane, so their ears are more visible.

Mum Roberta was selected to be paired with resident male Jayendra through the European Endangered Species Programme, which is run by a Species Coordinator and is supported by experts at other zoos across Europe.
