yeah, pretty much.
my rabbit was easy to potty train, so i am luck.
when i got her i noticed she always pooped in the same spot, so i put a litter box there with aspen chips in it, and lined it with some day. she has never failed to use it, unless i move her cage somewhere then she will potty in a diffrent place, just to tell me she wants her litter box over there. like, when i first started letting her have run of the house i didnt even bother with the litter boxes until she showed me where she wanted to go at. i just put the box there and that was the end of it.
