Before implementing any cat deterrents to keep the cats off your car by locating the owner of the neighborhood cat. Meet with the owner and inform them that their cat is being a nuisance and ask them to keep their cat indoors. Tell them any damage (scratches) on your car that they will be responsible. Most pet owners do not want to part with their money and they will keep their cats indoors and away from your car.

Replenish as needed.
