Stray cats spraying?
The reason cats spray is to mark their territory. If it is possible, put aluminum foil where the strays are spraying. Cats HATE the sound of their pee-pee hitting aluminum foil, so that should discourage the alley cats.



Your pet shop should have some cleaning agents that can remove the pungent scent of "eau de chat."
Reply:The strays are probably just marking there territory so do this get a $1 water bottle to spray the cats. Then spray them when they come to mark their territory, eventually they'll learn. It happened to my cats. Except I was teaching them to stay out.
