How do train a rabbit too go in a potty-box?

hi
i have a rabbit and when i first got him they told me how to train them…..what u do is put a litter pan in each corner of its cage and when he goes to the bathroom put some of the droppings in the litter pans so he can know thats where they belong and after time start taking one away by time but leave the litter pan that he uses teh most in there and always keep it in that corner….and once he is trained if he does have an acident and goes out of his litter pan dont b mad cuz they have mistakes just put the dropping in the litter pan.

also to warn u if u didnt know and u r thinking about getting a bunny they eat their poop for nutrisious reasons and u can google about that but they mostly eat those at night and they r called night droppings
