If you’re tired of coming home to find your favorite couch has been transformed into a scratching post, Pet MasterMind Cat Spray is the answer you’ve been looking for. This non-staining spray uses natural, plant-based ingredients to deter your cat from scratching where they shouldn’t. Its ingredients include jasmine, passionflower, and cat pheromones, so you can rest easy knowing that your furniture is safe—and so is your cat. Just spray it directly on whatever item or area you’d like your cat to avoid, and the product will begin working immediately.
Customers write that the Pet MasterMind Cat Spray works wonders. It gets most cats to stop scratching immediately, and most people aren’t bothered by the smell. It’s equally effective at getting cats to stop marking, and continues working for several days after the initial spray.
If you want a great deterrent in the form of a convenient spray, we’re fans of PetSafe’s SSSCAT Spray Pet Deterrent. This spray is motion-activated, detecting when your pet comes within three feet of it and spraying automatically—saving you the effort of remembering to re-spray an area to keep your cat away. Each bottle is good for 80 to 100 sprays, and the formula is safe and odor-free. It’s one of the easiest and smartest ways of setting boundaries for your cat, whether you want to keep them off a certain piece of furniture or out of a specific room of your house.
PetSafe SSSCAT Spray Pet Deterrent earns raves from buyers, who write that it’s stopped their cats from scratching or eliminating in inappropriate places. The motion sensor is reliable, and the bottle can be cheaply replaced when it’s depleted (rather than buying an entirely new unit). It works outside as well (some customers have even used it to keep raccoons at bay).
If you’ve been having trouble with the neighborhood strays or just want to keep your cat away from a certain area outside, try an outdoor repellent, like Nature’s Mace. This concentrate can be sprayed outdoors and makes anything it comes in contact with unappealing to a cat’s sense of smell and taste. It’s ideal for lawns and yards, but can also be used in a basement. It’s safe to use around people and plants (including vegetables) and is sold in ready-to-use spray bottles as well as larger containers of solutions.
Owners write that Nature’s Mace Cat Repellent actually works, keeping strays away even after they’ve been marking an area for weeks. While you do have to reapply for the product to stay effective, it’s an easy solution to an annoying, smelly problem.
Not only can cats cause a lot of destruction to your garden, but some plants are toxic to your furry friend. If you specifically need to keep your cat out of your garden, Systemic Animal Repellent Tablets should do the trick. While this repellent is rated for a wide range of animals, including deer and rodents, it’s also effective with cats. The product uses capsaicin, a natural component of chili peppers, to keep unwanted snackers at bay. The tablets should simply be buried next to growing plants, and absorb into their root system to remain active for an entire year. One 150-count bottle treats between 75 and 120 plants, although the number of tablets required depends on the size of each plant.
Systemic Animal Repellent Tablets have put an end to unwanted munching and have no adverse effect on a plant’s ability to grow. Just be aware that it should only be used with flowers and ornamentals, not anything you intend to eat as the capsaicin will affect the taste.
The Wikomo Ultrasonic Repeller Solar Powered Animal Repeller is a great way to keep outdoor cats (and other animals) away from your lawn and garden without using any chemicals. A motion sensor will catch when critters approach the off-limits area and an ultrasonic sound and flashing light will scare the unwanted creature away. It requires no chemicals or pesticides and is solar-powered so you don’t have to worry about changing the AA batteries. It has a stake that can be pushed directly into the ground, or it can be hung on a post or fence. It’s also entirely waterproof and comes with a six-month money-back guarantee if you’re unsatisfied for any reason. There are five settings with increasing frequency that you can change depending on the animal you want to keep away (a lower setting works just fine for cats).
The Wikomo Repeller is a humane alternative to other repellants and works to keep outdoor cats away from small areas, but know that you may need multiple devices for a large area, like a backyard.
Your cat provides endless love and affection, but that doesn’t mean you have to love when she ruins that new couch with her claws. Destructive cat scratching can be your brand new couch’s worst enemy, but Sticky Paws Furniture Strips are a great solution. Most cats hate the feeling of sticky or tacky material, so when they try to touch the legs of your couch and feel the Sticky Paws Furniture Strips, they will be immediately turned off. These adhesive training aides can be applied to any piece of furniture or carpet safely and discourages your fuzzy friend from pawing and clawing. Each package contains 24 single-use strips that measure 2 x 24 inches. The strips should be replaced every few months and are totally transparent so they won’t ruin the look of your couch.
Owners love this product because it’s safe for furniture and cats and eventually trains the cat to stay away, even when the tape isn’t there.
Whether you want to keep your feline escape artist away from the front door or would prefer your cat not to sneak into the nursery while baby's asleep, this radio fence can help you set boundaries for your home. It's compatible with the PetSafe receiver collar to remind your cat to stay out of the off-limit area. When your cat comes within 10 feet of the device it will send a tone and then a small stimulation to the cat’s collar to remind her to stay away. It will protect up to 20 feet diameter around the device, but you can increase the protection zone with additional transmitters.
Location When purchasing a cat repellent, you’ll first want to think about whether you need an indoor or outdoor product—or one that can be used in both locations. Certain products can only be used indoors, and others may need to be plugged into an electric outlet.
Coverage area Are you trying to keep feral cats out of your backyard or just trying to keep your crafty kitty off the kitchen counter? Some cat repellents are designed to cover small areas—a few feet, at most—while others can cover up to 5,000 square feet or more.
Behavior If you’re using a cat repellent to deter a certain behavior, such as scratching furniture or chewing on houseplants, you may want a product that’s specially tailored to your specific situation. For instance, there are sticky sheets you can put on furniture or foul-tasting sprays to help protect your plants.
