Into the lion's den.

Visitors to this private zoo in Buenos Aires can pet and feed dangerous animals.

The owner claims to be able to domesticate tigers, lions and bears by raising them alongside dogs.

He says he keeps animals passive by never letting them go hungry.

But critics say they're calm because they're sedated, and that this kind of interaction is risky for both humans and animals alike.
