(CBSDFW.COM) – A lion cub decided to play a little trick on its mother at Scotland’s Edinburgh Zoo.

The zoo shared the video on Facebook of the cub sneaking up behind its mother and then pouncing right behind her, causing the mother to jump in fright.

“Trying to relax when you have little ones,” the zoo said in the post.

The zoo is owned by the Royal Zoological Society of Scotland, which was founded in 1909. The zoo opened in July 1913.
