It might resolve on its own, as it could be a matter of them just littering up the rearranged area, or, you might have to take away the implicated rug near the litterbox.

I used to give my buns a towel next to their litterbox -it’s their favourite snuggle spot. They just couldn’t resist peeing on the fabric but leave the spot alone when its gone. I gave up and took it away.

I’d give it a week or so, then if they are persisting give up. Some buns just can’t resist viewing set ups like that as a litter box extension!

My 2 dutch boys do that. If you put a rug in, its their new litter box. If you dont put a rug in, back to the litterbox.

This can be really exhausting and you have my sympathies. My two went through an August until October Urine and Poo binge.

I had to change their litter set up and remove all the rugs. The rugs have been reintroduced, slowly, one at a time. I washed the rugs in a hot water and vinegar wash to remove any urine smell and washed the floors with vinegar. You have to get ALL the smell off, or they just urinate again.

Also, I know my two did their pee fest because we introduced our cat into the house. They used their urine as a way to mark against the cat.
They no longer do this – but it has taken months and persistent introduction between the cat and rabbits.

I gave up. I tried all different matters of bed and blankies…mine just pee on them. So we have hay and poopies in our dryer trap and I just wash them and put them back….mine just like peeing on fabric lol
