Instructions
Inform the cat's owner, if you know to whom it belongs, that you would prefer it if they did not allow the cat to roam into your yard and use it as a litter box. Be aware that sometimes this may help, while other times it may be futile.
Avoid attracting cats to your yard or property. Keep garbage can lids tightly closed and pick up all food scraps from outside dining events. Spray, on a regular basis, for bugs or other pests that cats may be attracted to as a food source.
Sprinkle your lawn with a commercial cat repellent such as Shake-Away, or use a spray such as Liquid Fence on your lawn. These type of products contain natural plant extracts that serve as deterrents to cats. Follow the product instructions when using these preparations.
Place a motion activated sprinkler in the area of your yard where you find evidence of cat activity. The sprinkler will come on when it detects motion, and will spray water on the unsuspecting feline, scaring it away. These type of products are designed to work during the day or night.
Place a length of chicken wire flat on the ground and stake it down, if the area cats use in your yard is a small one. This will deter felines from continuing to use this particular area, because they won't want to walk on the wire surface. Yet, they may start using a different area.
How to Stop a Cat From Using the Lawn as a Litter Box
In many areas, cats freely roam, visiting the yards of everyone in the area. While a homeowner might not mind the occasional feline traveling through his property, the prospect of a cat using his lawn as a litter box is, in all likelihood, unwelcome. Cat feces may end up on the bottom of your shoe, and also may harbor harmful parasites. Yet, there are harmless methods you can implement to deter cats from using your lawn as a dumping ground.
