New Item Called Traps

so this is not a bug, sorry. But think about this. so you make a thing called traps were there is small and big. small takes 1 iron and catches rabbits and foxes . And wont activate if a player walks over it. but a big one costs 2 iron and catches , cows, pigs, horses, sheep exc. But it will activate if a player walks over it. You are entirely free to change anything i just believe this would improve and benifit the game.
