Review on Ultimate Cat Repellent: Shake Away 9002020 20-ounce with Coyote/Fox Urine by Julie Watkins

I started researching cat repellents when one of our cats exploded by the neighbor's cats walking through the yard. I have tested similar products as well as electronic repellents etc. From what I've seen, the success rate didn't exceed 50%, regardless of the method. It all depends on whether the particular cat you're having an issue with is sensitive to the repellent you're using, meaning you can't know for sure if something will work or not. I figured it would be better to take a risk and buy a cheap item first, so I decided to try the coyote/fox urine crystals. You've done a great job for us. They need to be replaced every few weeks, especially during the rainy season, but they seem to keep cats well away from windows and doors. So I recommend trying this product if you have trouble with street cats. - but keep in mind that you probably only have a 50-50 chance that it will work.
