The Wildlife Heritage Foundation has released a video of its lions in a roaring competition at their Big Cat Sanctuary at Smarden in Kent.
The conservation group looks after more than 50 'big cats' at the sanctuary.
The video shows lions trying to defend their area of the site from approaching lions from another pride.
On one side of the site are Kafara, Manzi and Tiny, who are three brothers; while at another location on the site Themba, Joy and Sophia roar - warning the other lions to stay away from their cubs.
