A guide told the visitors that the 'two youngsters' were 21 months old. However, the male already weighed between 280 – 300 kg, the guide said.
"In the wild, their average lifespan is about twelve years," the guide continued. "in captivity, they can live up to twenty years."
Suddenly, the male lion leaps onto the top of the cage, just centimetres away from Campbell's head, causing a wave of nervous laughter from the group.
"Oh snap," Campbell says, as the lioness stares directly at him, sniffing at his head.
"I can feel her breathing down my neck."
Looking back up to the male lion, he captures the animal crunching on a bony piece of meat with its strong jaw.
"Is it good buddy?"
When asked how many lions the sanctuary had, the guide replied "fourteen".
