Do Ultrasonic Cat Repellers Affect Birds?

The simple answer is no.

One of the reasons you’re trying to prevent cats coming into your garden is probably to protect birds. Whether cats do it out of playfulness or violence, we know they love to go for birds so you might be looking to scare cats away using an ultrasonic cat repeller.

Of course, you don’t want to use one of these devices if it means you’ll also scare the birds away. But the good news is that they don’t have any impact on birds and the RSPB.

Do Ultrasonic Cat Repellers Actually Work?

Several scientific studies have actually been performed on ultrasonic cat repellers. A lot of people swear by them whilst others claim it’s just a marketing ploy and they don’t really do a lot.

Well, results show that they can work. They reduce the chance of a cat visiting your garden by 32% and reduce the total time spent in the garden by 38%. Studies also suggest that these percentages increase over time as cats learn to avoid your garden that contains the device.

Again, it’s a case of trial-and-error to determine whether or not they will work for you.

Which Ultrasonic Cat Repeller Should I Buy?

Fortunately, there are a lot of devices on the market for a range of budgets. Below, we have picked out our top 3 devices for you to check out. The first is from and tested by the RSPB. The other two are available for next-day delivery on Amazon:

#1: CATwatch Cat Deterrent

This is the only device recommended by the RSPB. They actually worked with the manufacturer over a two-year period to determine just how successful the device would be at deterring cats. Their study did confirm that it reduces the chances of cats coming into your garden.

It does, however, come with a hefty price-tag so prepare yourself…

#2: Pestbye Waterpoor Cat Repellent

If you want a far more budget-conscience option then check this out from Pestbye available on Amazon. It has over 5,000 reviews with two-thirds giving it 4 or 5 stars suggesting it is working for a fair few people. It has multiple settings so you can use it to deter difference animals with a dedicated ‘cat’ frequency mode.

It’s battery-operated so no mains feed required.

#3: Kawai Cat Repellent

This is very similar to the above device and is also available on Amazon at just over £20. The difference with this device is that it is solar-powered which has the added benefit of not needing to remember to check the batteries every few months.

It doesn’t have quite as many functions as the other devices but does what it says on the tin.

Summary

Of all the deterrents you can try, ultrasonic cat repellers are probably one of the more expensive options. If you’re really getting frustrated then it is worth a shot but remember that it only has a 32% reduction rate so there is a chance you won’t see any noticeable difference in your garden.

If you want to save yourself some money then try some natural, cheap cat deterrents first.
