Lions, tigers, and other big cats used in film and television are deprived of space in which to run and all semblance of their natural environment. Instead, they are confined to extremely small cages, and abusive training methods are typically used to suppress the instincts that make them so dangerous to humans, including their strong predatory drive. Big cats are known to have been trained through food deprivation, fear, and punishment with whips.
When big cats grow old and are no longer useful to their trainers, they are usually cast off to seedy roadside zoos or other substandard facilities. Tigers are sometimes killed for the sale of their skins, organs, and other body parts on the black market.
