Showing off in a watering hole at his home, Zien leaps into the air as 50-year-old Alex awards him with a meaty treat
His close relationship with the animals has allowed him to develop a unique bond of trust and intimacy with animals like Zien.
'We are really close but you know there are certain things they know they mustn't do and certain things you know you mustn't do, so you get to know each other,' said Alex.
Despite his young age Zien already weighs a whopping 90 kg and is fed twice a week on fresh meat to mimic the eating habits of lions in the wild.
The 208-acre Lion Park houses over 300 animals including lions, cheetahs and hyenas.
Skilled Alex moved to South Africa in 1999 and has been an animal trainer for 35 years
