My cat started having accidents in our hallway a few weeks ago, due to the sensitive food we had her on and ever since, shes been going there to do her business. We switched her food to another sensitive stomach brand and she really enjoys it, but her poop is still a mixture of runny, firm piles. She pees in her litterbox and poops in it on and off now. We bought a bottle of Nature's Miracle Advanced Stain and Odor Eliminator and tried it out on the spots, but she still goes back and poops in other places in the hall. We even tried saturating the whole hall twice, with no luck. Aside from that, her coat is shiny and shes still very sassy. I am at a loss on what to do for her at this point.
