I only have one rabbit and she is a 4 month old dutch dwarf.
She was spayed when she was 2 months old.
(I took her to the vet thinking that she was older than 2 months, but they just went ahead and did the operation on her anyway).
Up until couple of days ago, she has been very good with the litter box.
She would poop there about 90% of the time and would pee close to 100% in the litter box.
She had occasional droppings here and there inside her cage but I did not think much of it because she never had an accident
outside of her cage and also I thought it was just a bunny thing to do.
Then just couple of days ago, she started pooping outside of her cage.
She would drop them just inside the play mat as if she was marking territory.
The frequency was too great to consider that as an “accident” It is clear that she was doing it on purpose.
But I was not sure if it is health related or if she’s just unhappy about something.
The thing is, nothing about her living arrangement has changed.
She’s still living in the same old cage in the same rabbit room.
I also let the cage door open for over 10+ hours a day every day.
Only thing that has changed is her diet.
About a week ago (so couple days before she started pooping outside of her cage),
I bought a different brand of orchard grass and also added in the timothy hay in her diet.
Her diet consists of Orchard Grass, Timothy Hay and some fresh veggies like cilantro and romaine lettuce.
Also, the day before this strange behavior started, I attempted to bathe her.
I brought in a little tub and put it down on the play mat and washed her feet (which seemed to be covered in urine).
She did not enjoy this.
Another cause may be that on the day (maybe a day before) she started pooping everywhere inside the mat, we had a pest ban guy over that sprayed things inside the walls (they have a system where they spray some chemical from outside the house and it spreads inside the walls. )
Can any of the above reasons result in this behavior problem?
Also, for couple of days, she only pooped on the mat. But today, I realized that she peed twice on the play mat as well!!!
But she did not pee or poop on the carpet.
Ugh… why do you think she’s doing this and how can I fix this behavior?

This is her cage and the litter box inside.
Yeah the set up is weird but its small litter box + hay dispenser inside a big litterbox.
The blue water bottle is there to prevent bunny from pooping / peeing outside the small litterbox.

This is the rabbit room. It’s about2.5x the size that is shown in this picture.
But the round table cover is what I have been referring to as “play mat”
She is not pooping / peeing on the carpet. She’s just doing that inside the play mat.
But I’m afraid that she’ll eventually move into going to the bathroom on the carpet as well.
Ugh Please HELP!
