Lucy did this right after she was spayed. Honestly, it took a good couple of months to fully kick the habit. Luckily, peeing stopped within a month or so, but the poo-ing took a little longer.
I got like, 5 litter pans and scattered them where she would typically have her accidents (or on purposes, depending!). I got the pans from the dollar store, the kitty ones. I put a lot of treats and hay in each. Any time she looked like she was poo-ing (she gets this…look, it’s weird) I’d pick her up and move her. Sometimes she was in the middle of a deuce, sometimes she wasn’t. Either way, she’d sit there for a few, then hop out. Even if she didn’t do anything, I still praised her like she just took a golden doodie.
If she’s still peeing on you guys, keep a box like, RIGHT by you. When she starts to pee, put her and hold her (gently obviously) in the box until she’s done. Then praise her, because the last behavior was peeing in the box, so she’ll be excited that she got praise for peeing in a box.
Lucy still occasionally will drop a few excitement poos, or she’ll drop a few right outside the cats box, because it irritates the cat.
Hopefully something will work, I know it’s rough
With Lucy I was still at my parents house, and my dad didn’t really understand completely, so in addition to trying to re-potty train my rabbit, I had my dad in my ear WHY IS SHE PEEING AND POOPING GAAAAH. She’ll get there again
Hang in there
