PetSafe SSSCAT 1st & 2nd Generation Automatic Spray Pet Deterrent Refill Can, 1 count; Keep your pets safely away from off-limit areas in your home by ensuring you don’t run out of deterrent spray. Simply swap in a new PetSafe SSSCAT 1st & 2nd Generation Automatic Spray Pet Deterrent Refill Can when the old one’s empty, and you’re good to go. Each can includes up to 120 sprays that’ll help guide your pal away from unwanted areas. Just place the spray holder anywhere you want to keep curious paws away. When your furry friend comes within 3 feet, it will emit a quick, odorless spray to alert them that they are approaching an off-limits area. This spray is safe for pets and doesn’t leave a residue, so feel free to place it practically anywhere indoors. Added bonus, these newer refill cans also work with the 1st-generation SSSCAT spray head, so you can use them even if you have the first generation model.
