Great math!

You overlooked the sentient-omnivore-who-leaves-makeshift-toilet-paper disgust multiplier.

If that factor is set to 100 (consider how inoffensive horse pucky is vs finding a year-old's soiled diaper) then we're talking 0.01% of 115K humans matches the horses.

That's only 11.5. Did 12 people drop one in Central Park today? That's one duece for every 70 acres.
