Asian lion cub at London Zoo

One of the main reasons I wanted to go to London Zoo was to see the baby Asian lions they have at the minute. They were born in October 2011 so they're growing up fast but they are ludicrously cute. When we got to the lion house, it was late afternoon and they were snuggled up in a big pile of fur with their mum in a patch of sunshine, right up against one of the viewing windows in their enclosure.

Asian lions are super endangered. Although they used to have a range that continued as far west as Greece and Italy, these days they are only found in the wild in the Gir forest of Gujarat, India; a census of the lion population in 2011 indicated that there were about 411 Asiatic lions in the world, up from a total of 234 in 1936 when the first ever census was taken. They are threatened by habitat destruction, and are killed by electric fences and open wells.
