SSSCAT Cat Repellant Deterrent Kit Includes:

Kit includes SSSCAT aerosol can, electronic motion detector, instruction booklet and warranty card.
Refill your PetSafe Ssscat Cat Spray Control System to keep your cat off countertops, plants, and away from anything else you need. Each can has 200 sprays. 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.
The SSSCat solves all these problems!
Our cat would frequently prowl our counter when we had a our backs turned, and who knows where his feet have been (well, I think you might know). In addition, he ate half the sponge on the sink and got sick. We were also concerned that he might eat human food that was harmful to him (like food with garlic) when our backs were turned.

So we thought we needed to prevent him from doing this in the future. A little research on Amazon turned up the product "Ssscat" which seemed like a harmless way to keep him off the counters. Ssscat is an electronic device that mounts on top of can with pressurized air in it. When anything moves in front of it, a short burst of air is emitted.

So I setup my newly arrived Olympus OM-D E-M5 on a tripod and started the video just before we left to eat at our favorite local Mexican restaurant. When we came back, the video we saw had us literally rolling on the floor.

Its amazing how cats can pop straight up, seemingly defying gravity. If you watch the slow-motion of the video carefully, it looks like Shasta is going to fall off the counter but in the end, both of his back feet are firmly planted on the edge of the counter as he launches himself away from the "danger".

Basically, both devices look the same. One is gray and the other is black, but the shape, design, and everything else are (almost) the same. Yep, the printed on the devices are the same. They are both owned by the company MultiVet, which has recently merged with Innotek and PetSafe – the manufacturers of sssCat.If you read older forums about these devices, you’ll find out that sssCat once also had a “beep only” mode, but later they started to manufacture ones without it. We’re not sure why, because the beep mode makes a huge difference. It even helps to save you money. Many cats make the association between the beep and the burst of air very quickly and, as soon as the first can is empty, you can set the device on beep only mode. Your cat will head away instantly, just after hearing the beep.sssCat normally lets off a burst of air when it detects motion. StayAway, however, sounds a short “beep” and then sends a burst of air. Soon, the cat learns that every time he jumps onto a counter, the beep will sound and it will be followed by a burst of air.The motion-activated spray safely and automatically keeps pets away from rooms, furniture, and areas in your home. Set it on the counter to keep your cat from jumping up, or place it in the doorway to the living room to keep your dog out of the room and off the couch. It's easy to train your dog or cat to stay out of certain areas.
When your pet comes near the Ssscat, he'll feel a quick burst of harmless but startling spray. The spray reminds your pet to stay away. The adjustable spray nozzle can detect and deter pets from up to 3 feet away. To refill the unit, make sure the unit is turned off. Hold the refill spray can upright and firmly press the nozzle down into the refill port. Hold for 15 seconds or until unit is full, then remove the can. If spray leaks out, you may need to press harder to complete the seal.Both sssCat and StayAway are not divine devices, and sometimes they may miss a cat running alongside them. Based on our observations, StayAway was more likely to miss than sssCat. However, that just refers to a case when you want to keep a cat from crossing a certain border. If you want to keep a cat off a counter, or away from a closed door, both work every time.This terrific product is perfect for dealing with minor stubborn behavior in your cat. I didn’t like our cat going up on the counter behind our kitchen sink to look out the window, but every time I went outside, there she was laughing at me. I tried many different deterrents, but she was like the Borg from Star Trek. She would just adapt. SSSCat solved the problem.
