Smith has faced several health challenges in recent years but you wouldn’t believe it when he caught sight of a Halloween pumpkin on one of his platforms at the ADI Wildlife Sanctuary and launched himself at it.

This picture shows why enrichment is so important for captive animals, giving them different experiences and keeping them mentally and physically stimulated.

Ten years ago Smith was the most famous lion in the world after a clip went viral of him dragging an audience member around a circus ring in Peru. A particularly irresponsible circus act, in which Smith was meant to jump over a member of the audience, went wrong. As a result ADI rescued Smith and all of the other animals that remained in the circus.

Ten years on you can see just how powerful he is and just how stupid it was to put a member of the public in a circus ring with him!

Happy Halloween Smith.
