also i was used to just referring to them as "steers" but ox i knew was a cow kinda thing that pulls stuff, especially ploughs, just sorta thought they were special breeds like how donkeys and horses are close but not that close, close enough you can breed them but not close enough that the offspring - what are they called, or am i getting it muddled up and donkey is a cross breed of a horse and an ass... lol
