You can search YouTube for videos of the Harbin zoo in China. I’ve seen some of these where a dump truck drives into the big-cat enclosure and dumps a live prey animal (donkey, sheep, etc.) right into the middle of a pack of hungry cats. The cats aren’t exactly hunting, but they do get to kill their prey. Not sure what the motive is for the zoo to do things this way, except maybe it’s easier to let the cats deal with a live animal instead of having the zookeeper kill/butcher the animal and then have to clean up.
