YES,he's really stubborn.He will pee in every single corner he gets the chance to,it's insane.
My female is over a year old [not by much,she's tidy] but my male isn't a year old till this summer,& he's not clean
Alrighty, this is my method for stubborn rabbits (though it'll work better when he's fixed):
Day 1- Place a litterbox in every corner of the cage. Hay should be put in all of them and you should try using a few different litters (like one can have aspen shavings, one can have YN, etc.). This is to see what kind of litter he prefers and where he likes to go to the bathroom.
Day 5- By this point you will probably notice that at least one of the litterboxes isn't being used as much. Stop putting hay in that box.
Day 7- Remove the litterbox that isn't being used and place a large food dish there instead or a different object that will block the corner. If he starts peeing there you'll have to put the litterbox back and wait a little before trying again.
Day 10- Once again, stop putting hay in the litterbox he doesn't use as much.
Day 12- Remove the neglected litterbox and place a large box or another object that will block the corner.
I think you get the point, hehe. Repeat steps 5 and 7 until there is only one litterbox left. Remember to have large, heavy objects in the corners without a litterbox.
After a couple of weeks you can start removing the objects that were blocking corners if you need to. Remember to always have hay in the box, clean any accidents really well, and place all stray droppings into the litterbox.
If at the end he is still using two or three litterboxes find the one you think he's using more and only put hay into that one. When he goes in the other ones dump the dirty litter into the one you want him to use.
I hope this helps. I made it up and so far it's worked with two rabbits...neutered males.
