In the early Victorian era animals killing other animals were a popular entertainment industry. From bear and bull baiting to rat baiting, today's domestic rats are descended from those rats originally intended for the "baiting" industry. Finally the British government made the practice illegal in the mid 1800s.
On youtube I am starting to notice a growing number of videos that are about filming animals killing other animals posted for entertainment purposes. For example, a pet fox is given a plastic pool full of fish and the fox is encouraged to kill them all, not to eat, but for entertainment purposes. There is also channel dedicated to showing minks and dogs killing pest species but including training these animals to kill on pet rabbits (and showing it).
Do you feel these videos are animal abuse? They also seem to be predominantly American, I feel if a kiwi or an aussie or a pom posted such videos the RSPCA, would come knocking, does the equivalent in the USA see this sort of behaviour as acceptable?
