PetSafe Ssscat Cat Spray Control SystemKeep your cat off countertops, plants, and away from anything else you need with the PetSafe Ssscat Cat Spray Control System. When your cat gets too close, a spray is emitted which will teach your cat to stay away from that area. The PetSafe Ssscat Cat Spray Control System utilizes a motion detector that quickly dispenses an odorless spray to startle your cat and educate them that they are not allowed there. The sensor has a 3 ft. range so as to prevent any unwanted spray occurrences. An added bonus to the PetSafe Ssscat Cat Spray Control System is the adjustable nozzle which allows you to have more control over the corrections. Each can has 200 sprays and the motion detector uses 4 AAA batteries (not included).
