Cat poop may all smell the same to us, but cats can tell their waste apart from another's thanks to unique
chemical scent markers called pheromones, which are present in their urine and feces.
The absence of dog
scent aside, these rooms further reduce feline stress because they may be equipped with diffusers that disseminate a synthetic version of the normal pheromones given off by cats as they rub their cheeks against people or furniture; this pheromone serves as a
chemical marker that signifies safety, contentment, and familiarity.
