"good if you have a pet or housemate who sometimes poops inside"

I have a pet (cat) that unfortunately poops just outside her box most of the time, despite a lot of different ideas and approaches with the help of our vet. She's old and has lower back pain issues. It ends up on a litter mat or the wooden floor, so it's not that hard to clean up.

If I had a housemate that pooped inside not in the toilet, they would need to be even less able to manage their shit, so to speak, and more loved than our cat, or they would be out of here very fast.
