Fact 6: There is A blood sport in the USA in which tons of rattlesnakes are killed in public to gain attention to overpopulation. although rattlesnakes can be dangerous, were responsible for them to become dangerous, since they attack to defend themselves and their young, not to attack to attack. rattlesnakes are also very social amongst their species, having been known to create friends, and other things. rattlesnake populations are dwindling as time goes on. (Oh yeah i forgot to tell you one thing, once the rattlesnakes are killed there in that sport, people force kids to put handprints of rattlesnake blood on walls, isn't that messed up)
