Do odors ever completely disappear or are we making the world slightly but permanently smellier each day?

Do smells/odors ever truly disappear or do they just dissipate to the point that eventually we cannot smell the original odor and each one is permanently adding however miniscule an amount to an overall smell on the planet?

Why does cat urine (specifically “spraying”) seem to never stop giving off an odor? Even after repeated washing?

The real questions IS: does snot have a smell of it’s own?

And if so: do we truly even know what anything smells like? Or do we smell everything with a slight snot taint?
