I know I’ve mentioned my struggles with litter training Oreo before. Well we’ve made zero progress and it actually seems to be getting worse 
Her cage is set up with her litter pan on one end and her food bowls (one each for pellets, water and veggies) are lined up at the other end. I’m using carefresh in the box and have hay in there as well. I’ve put stray poos in it and soiled tissues. She loves to sit, groom, sleep in the box. However, she keeps pooping on the other end of her cage, directly in front of her food bowls, as if she’s backing up to the bowls and going. After a few days, I thought maybe she just prefered that end of the cage and swapped the box and bowls to opposite ends. Well, she also switched along with it! Still going right in front of the bowls. Well I just went in to check on her and noticed that not only did she poop in front of her bowls but she had peed IN her water bowl!!
I know others have mentioned that her hormones may not have calmed down yet from her spay about 3 weeks ago. I’ve tried the herding into the box thing as much as possible except that it’s so hard for me to tell when she’s peeing/pooping until after it’s happened. The herding I have done makes her VERY upset as she’s extremely aggressive about hands in her cage. I’m planning to get a spray bottle tomorrow to start using but I’m at a loss of what else I can do. I want her to be litter trained but I REALLY don’t want her to keep peeing in her water!
