The cub in this photo is just six days old, utterly adorable

Quite a while ago, a zoo in Thailand witnessed the birth of several baby lions, which have now grown to be five months old and in perfectly good health.

However, the zoo's staff takes great pleasure in recollecting what these tiny big cats used to look like when they first came into this world: toothless and utterly adorable.

The lion cub in this picture is a female named Ying Yai (which means “Elder Princess”).

Zoo keepers explain that, when this lion cub posed for the camera, it was just six days old and its teeth were only just beginning to grow.

Just for the record, the Hollywood-smile Ying Yai displays in this picture is in fact a yawn, although some argue that the cub was trying out its roars.

“Laying on the ground I was able to catch the fully extended jaws of Ying Yai exposing her teeth they were just beginning to show through. I called the photo “Roaring Practice” for the fun of it,” Ashley Vincent, the man who snapped this picture, told members of the press.
