1. Ssscat! Cat Repellent Training System by Multivet
2. Tattle Tale Sonic Pet Training Alarm
Tattle Tale depends on a combination of vibration-based detection plus a "startling" 2 second tone. The unit operates on a 9V battery, and has a hi-low adjustment for the vibration sensitivity. A sensor detects vibration in a surface or object without apparent motion. The sound then startles the cat into leaving the area, while also alerting the owner. Tattle Tale can be hung or placed on any horizontal surface. I haven't tested this unit and wonder at its potential sensitivity on a tile countertop or floor. One Amazon reader remarked that on the third day she found her cat sleeping peacefully on the sofa cushion right next to the unit. (I may or may not be reviewing this product.)3. Wire Loom
Wire Loom is the technical name for split tubing used to cover electrical wires and cables, and is an excellent means of preventing dangerous shocks from cats nibbling on wires. It isn't exactly a cat repellent per se, but it will protect electrical cords from damage, and more important, protect cats and kittens from shocks.
Wire loom is flexible, comes in various colors, including clear, and several sizes from 1/8 inch to 2 inches, and in lengths from 10 to 100 feet. This eBay merchant has ongoing sales on Wire Loom. If this link happens to be broken, an eBay search on wire loom split convoluted tubing should turn up a current link.
4. Sticky Paws Cat Repellent
5. Bitter Apple Spray Cat Repellent
6. Catstop Automatic Outdoor Cat Repellent
This ingenious cat repellent is motion activated and utilizes ultrasonic noise pitched to a frequency only cats can hear (21-25 KhZ. It is safe for outdoor use and includes an optional stake for mounting in lawns or flower beds. The unit covers an infrared sensing angle of 80 degrees, and detects movement up to 20 feet away.
What I liked best about Catstop is that it is battery powered, eliminating the need for clumsy extension cords. (A 9 Volt battery will last up to 4,900 activations.) You can also order an optional AC adaptor for this product. It comes with a 30 day money-back guarantee and a two-year warranty.
7. Jumpo Trainer Cat Repellent
Jumpo Trainer is a rather simple device that operates on the principles of physics. A strong bungee cord connects two hard plastic asymmetrical pieces. When stretched tight, the pieces lock together and can be placed anywhere you'd prefer cats not to be. A very light touch to the unit causes the two pieces to jump high into the air, landing noisily. Jumpos actually were first marketed to keep birds off boats, patio areas, etc. However, it was soon realized that they also deterred cats and other critters.
Jumpos should be handled carefully, because they sting if accidentally sprung. You may want to covered set Jumpos with a towel or other covering to prevent accidental injury to cats. One or two uses are usually sufficient warning
.8. ScareCrow Outdoor Cat Repellent
ScareCrow, which looks more like a mynah bird than a crow, in my opinion, is an a motion activated sprinkler that will instantly respond to intruders with a burst of water. Great for keeping stray cats out of your yard or your own cats within boundaries inside your yard. It has a 105 degree detection range and about a 35 foot squirt range, so you may need more than one for maximum protection.9. Shake-Away Outdoors Cat Repellent
Shake-Away claims to be the "strongest cat deterrent in nature," and I have to agree, judging by the ingredients. Shake-Away is a granular substance with the odor of fox and coyote urine. Even territorial cats are smart enough to stay away from areas previously marked by much larger predators. One 20 ounce bottle will cover as much as 600 linear feet. Shake-Away is non-toxic to humans, animals, and flora. Like the "real thing," applications should be repeated over time or after heavy rain.
I've tested it, with limited results, probably because the applications weren't repeated frequently enough.
