Contech CatStop Ultrasonic Outdoor Cat Deterrent

I have used the CatStop for my front yard for about a year and recently purchased 2 for my newly resodded back yard. I have been so pleased with all that I have purchased. Gone are piles of stray cat poop and the smell of urine. No longer is all the mulch dug up in the gardens. No longer is the smell of urine overpowering you at the front door. I live in a humid area and the stink was awful. In the back yard, it is so nice not to have to clean your shoes off all the time.

Finally, no more scooping out odiferous cat feces out of the flower beds. This CatStop works great even though it's exposed to the constant rain

I think this works. The light will come on if I pass in front of it and I haven't noticed the neighbor's cat as much. I have seen it twice but both times it was on the perimeter of where this device wasn't covering. I then moved it forward and haven't seen the cat since.

I purchased this sound device as a last resort and crossed my fingers that it would rid me of my disgusting cat poo problem and help me to avoid resorting to extreme measures to stop it. It works! The first time it went off on a cat in mid poo, I heard the meow and the animal left a trail of poo as he ran away. That was the last time the cat and is friends used my lawn as a litter box.

Its been six weeks, the longest, any measure I've taken lasted. Although the battery died after 3 weeks - 9 volts are expensive, the cats avoid my lawn. I watch them through the window as they approach my house and take off running to get across quickly,so that they don't have to hear the sound. They have been successfully conditioned to avoid my lawn. I'll give it another week before I replace the battery, just to keep those pesky cats in check.

The neighborhood cats (6+) decided that my landscaping was a great place for their toilet. I was fed up with scooping poop, the smell and flies. Yuck! CatStop is great! It's not perfect - I wish the range was a little wider, but it works. I purchased 2 units, one for the front bed and one for the back yard. The unit in back seemed to get stuck in the on position, so the battery died quickly, however the battery was replaced and it is working fine. The cats that liked the back yard seem to have found another yard to make their deposits. So I moved the 2nd unit to the front (larger) bed to cover that area better. So far so good!
