Since the lion arrived, which is three years now, I haven't really left the camp," says Gruener.
"Sometimes for one night I go into the town here to organise something for the business, but other than that I've been here with the lion."
The lion he has devoted himself to is Sirga - a female cub he rescued from a holding pen established by a farmer who was fed up with shooting animals that preyed on his cattle.
"The lions had killed the other two or three cubs inside the cage, and the mother abandoned the remaining cub. She was very tiny, maybe 10 days old," Gruener says.
The farmer, Willy de Graaf, asked Gruener to try to save her and so he took her to a wildlife park financed by de Graaf and became her adoptive mother, "feeding her and taking care of her".
"You have this tiny cute animal sitting there and it's already quite feisty," he says. "It will become about 10 times that size and you will have to deal with it."
She's much bigger now, but when Gruener opens her cage she still rushes to greet him - ecstatically throwing her paws around his neck.
