“Cats do walk through feces and urine in litter boxes and then track it around the house.”
That’s only because the litter box is an abnormal and unnatural constraint put on them. Even then, they bury their waste in a litter box, just like they do outside under natural circumstances.
The scenario you describe above is due to owners not cleaning their litter boxes. A cat would never do that under normal circumstances.
