Unfortunately, these lions are just a small fraction of the thousands who are killed each year for the canned lion hunting industry, many of whom face similar conditions to those at the breeding facility - or worse.
Masha Kalinina, an international trade policy specialist with Humane Society International, told The Dodo that there are around 200 lion breeders in South Africa, many, if not all, of whom are involved in the canned hunting industry. Between 6,000 and 8,000 lions are currently living in captivity at breeding facilities like Slippers', with less than 20,000 wild African lions left in the world.
The lions' lifespans are often cycles of abuse. As cubs, they're snatched away from their mothers - who are bred constantly - and are often rented out to tourist facilities for use in cub petting or selfie attractions.
As they grow older, they transition into props for "lion walk" attractions, which allow tourists to take walks with the captive-bred adolescent cats through their supposedly natural habitats.
