Thread: Best way to eliminate old urine markings?

It is a terrible problem with no solutions. The neighborhood association tried a trapping campaign a few years ago but that failed, as euthanasia alone will not lower the numbers (nevermind that it is cruel and wrong). One woman on the street behind ours has taken in several and had them spayed and neutered, but then other neighbors get angry when they find kitty poo in their gardens or paw prints on their cars. Still others try to say that outside cats kill songbirds and other animals, but we feed birds and have a regular stream of finches, woodpeckers, jays, wrens, and all kinds of birds so that isn't true. And what if the neighborhood did eliminate all stray cats? It would be a matter of time before mice and rats take over, then they would be complaining about that! Our house is next to a hair salon and the owner loves our cats because they do hunt mice and keep them from coming into her business.
