Step 1
Get the cats neutered. Feral cats who have been trapped, neutered and returned no longer need to fight with other male cats or mark their territory by spraying.
-
Step 2
Use electronic deterrents. Electronic devices that make a high pitched sound or spray water on the cats as they approach will keep them away from specific areas, like parked cars or the sides of buildings. Most pet supply stores sell safe, effective pet deterrents.
-
Step 3
Plant Coleus Canina around the perimeter of the area you want to protect from cats. A member of the mint family, Coleus Canina is sometimes called Scardy Cat. It smells offensive to cats and other animals and has proven to be an effective repellent.
-
Step 4
Grow Rue (Ruta Graveolens). Many cats hate the smell of this herb and will stay away from it.
-
Step 5
Plant catnip. Catnip is a "friendly" scent and should keep the cats from spraying the area where it's planted.
