I'm sure it was the raccoons that moved the mothballs... from the rockery around the pond to the lily bed a few feet away. Fortunately I haven't noticed a raccoon problem for the past several years. They are as bad as cats for stinking up the gardens...
Guess I won't bother with the litter box idea then. Probably not worth bothering with mothballs either since it has done nothing but rain here lately. Anyway, the poop problem extends from the house foundation across the gardens and lawn to the sidewalk. The sidewalk and driveway are the only places they seem to avoid.
