Cat Repellents that Work
Unlike some other pest repellents, cat repellents really do work, keeping your yard free of cats and the risks associated with the mess they leave behind.
There are a number of options however, and depending on the area to be protected and other factors, the decision of which cat repellent to select can be bewildering for a gardener. With this in mind, we will clear the confusion and point you in the direction of the best solution for your own circumstance.
First of all, we will look at the most inexpensive and easiest solution - powder. There are a number of powders available that are designed to deter cats. They do this by creating a smell not dissimilar to the smell of a typical predator, such as a fox. This alerts cats into thinking that the area is not safe for them, and they are encouraged to leave the area rather than make themselves at home. The disadvantage of using a powder, or granules, is longevity; heavy winds and rain can drastically reduce the effect of the powder, and mean frequent re-application if you live in an area subject to wild weather. In a typical situation, to maintain effective protection, you can expect to re-apply powder around every 4-5 weeks.
The next solution to consider is an ultrasonic device. These come in a large range of prices, but as they do not require re-application like a powder, their longevity makes them more value for money. When these devices were first released, there was some debate over whether they worked and could really deter cats. Thanks to a cat repellent study however, there is no doubt that these devices do work, and that cats find the silent-to-humans high pitch squeal uncomfortable, and will move on to another, more peaceful location!
Finally, there are physical measures such as water deterrents. These work by spraying a jet of water whenever they sense the movement of a cat nearby. While the cats get a fright, there is no physical harm done, making water devices one of the most fool proof and effective measures. There are two downsides to this however. Firstly, water devices obviously require a water supply to work! If there is not a supply of water available however, some units collect rainwater and are solar powered. Secondly these are the most expensive solution to keeping cats away, however, as they are 100%: effective, gardeners are usually willing to accept the outlay to keep their gardens clean.
In summary therefore there are plenty of options open to gardeners to keep cats out. Powder is cheap and quick, but requires re-application, ultra-sonic devices are proven effective and water devices offer the discerning gardener the absolute best in cat protection.
