I too live in the area. And yes there are alot of strays. We have had the same problem with cats spraying on our stuff. It is one particular cat. Haven't seen it in a while so maybe he found a home. We have a cat that loves to be outdoors, but he is neutered and declawed. We have tried to keep him in but he just cries. Please do not be mean to these animals, some of them had to have come from somewhere at one point in time.
