In the UK, only a few circuses still have wild animals but around the world it's a different story.
Hayley's been to France to follow the journey of two lions who have been rescued from a circus and are on their way to a new home.
The only problem is, their new home is over 500 miles away at a wildlife park in the UK.
How will lions Brutus and Clarance get there? Hayley tags along to find out.
