Is the water bowl still in the same place? Willow won’t poo in her box if her water is near it. She wants her water several feet away from the litter box. Hay in box.

I agree with Mimsy. Sometimes a change in “furniture arrangement” may not be to your bunnie’s liking. Guin poops outside her litter box when the border of her area is fleece. So when I replace the 12-inch wide border strip all the way along the walls in her bedroom – with towels instead of fleece, she poops in her litterbox again. I’ve just added 3 rabbits to “her” room, so she is pooping EVERYWHERE again. Point is – the weirdest furniture setup fetish coudl cause yoru bunny to poop outside the box. It’s their way of reclaiming what us humans have disrupted.Do you still have the old water bowl?

I’m not sure about your cleaning schedule, but I know my older girl a few years back decided that my level of cleanliness was no longer acceptable to her. So whenever she felt like the box was too dirty, she would just stop using it and go directly outside of it. She especially started getting a dislike for when her bonded friend would use the box too much before she got around to using it.

A new item could’ve done it too. I made the horrid mistake of getting them a new litter box once that wasn’t identical to their old one and they just would not use it. It was the same size and the same height but the outer lip was just ever so slightly different. I did everything to get them to use it! Eventually I had to go and buy the exact same style of litter box they used to have and all was right with the world again. Thankfully it was a common brand!

In other words, I have a lot of poop all over my floor a lot more frequently than I’d like.
