Cockfighting is not legal in the United States, according to The American Society for the Prevention of Cruelty to Animals. It is illegal in all 50 of the states and is a felony offense in 40 states and the District of Columbia, as of 2015.
Louisiana was the last state to make cockfighting illegal in the United States, states Reuters. The ban took effect in 2008, following a similar law in New Mexico earlier that year. In 38 states and the District of Columbia, owning birds for the purpose of fighting is prohibited, notes the ASPCA. Being a spectator at a cockfight if there is gambling and drugs involved is also prohibited. In 43 states and the District of Columbia, it is a misdemeanor charge to be a spectator at a cockfight. Cockfighting remains legal in many other countries, such as Mexico, France and Puerto Rico, where the sport is still popular.
