This is enough to warm even the wildest of hearts.
Deep in the African bush a lioness gives giant hug to the two men who saved her.
As a cub, Sirga was driven out of her pride and rescued by Valentin Gruener and Mikkel Legarth who could not stand by and watch her die.
Now the 110lb lioness has developed an incredible bond with the pair who are fighting to save her species in Botswana, southern Africa.
Sirga treats the two conservationists just like she would other lions and with their help she can now hunt for prey on her own.
She is now a beacon for hoped success of the Modisa Wildlife Project, founded in Botswana, Africa, by Mr Gruener, from Germany, and Mr Legarth, who is Danish, with the hope of saving the lion population.
Botswana is two and a half times the size of Britain and has vast areas of wilderness - but already increased farming is bringing lions and man into more and more conflict.
The Modisa Wildlife Project has been working with local farmers to find a way long term solution.
The plan is to relocate the lions which are coming into contact with farmers to one large protected area where they have enough wild prey to feed on.
Their work has now been documented by photographer Nicolai Rossen who himself got up-close-and-personal with the predators.
Mr Legarth, 30, said his bond with Sirga was just like as if she was part of his pride.
He said: 'A pride had three cubs and two were killed before Sirga was abandoned without food. It happened on our land and we could not standby and watch her die.'
'In Botswana all lions are protected by the government - like swans being the property of the Crown in the UK. This also makes moving them a problem.'
'What we have now are 10,000-hectare plots with 10 to 15 lions in fenced enclosure, they are wild lions but we do have to feed them.'
Mr Legarth added: 'We are located on a 10,000-hectare farm with lions, wild dogs and leopards that has been saved from certain death. We are now looking for sponsors that can support us with a long-term solution for those animals.'
