We just recently got 2 bunnies, both female, not neutered, not litter-trained, and we were told they’re around 9 weeks old, they’re bonded pretty well without any effort. Their names are “Snowball” and “Izzy”
We purchased a litter box and I put it in the left hand corner because that’s where I saw most of the poop and urine. There were stains in the right corner as well, but I figured (and hoped) it was from the water bottle placed above that spot. However, a few days ago I removed the water bottle and switched to a bowl and still found wet bedding there.
So today I did the big weekly disinfectant clean with a vinegar solution and placed the litter box in the right corner thinking I was incorrect the first time around. But I just went in there and found pee stains and droppings in the left corner.
So my question is, is it possible that each bunny has chosen a corner of their own instead of sharing the same one? I mean, logically it makes sense if rabbits are as possessive as I’ve been reading but I’m not excited about it since I’m apparently going to have to build a custom litter box if that’s the case 


Any help would be appreciated. We’re technically first-time bunny owners. Yes, they were purchased during Easter week, but it’s actually something we’ve been researching and thinking about for a while. The timing with Easter was just happenstance. And I say technically because I owned rabbits when I was like 10, but I see now how my parents let me do everything wrong
