Top 6 Best Cat Scarers and Repellers – Details comparisons

Last Updated on

Cats are cute and cuddly but sometimes they can be little imps. They can soil your garden and turn it into a museum of cat excrement. We cannot blame them for their ways but you can try to keep them stay off your garden. Using cat repellents has been a practice for many years now and they have proven to work but we have found that using a combination of 2 or 3 usually works better than just using one cat repellent or repeller.

Finding the best cat repeller is another thing as some products have been deemed not up to it or simply not the right product for certain situations. That's because cats respond differently to different repellers, meaning you need to find the right product that will put off the cat or cats you have problems with. 

In this review, we will show you which repellers we think are the top cat repellers available in the market. They vary in how they work as well as in design, but they are all humane cat scarers that will never cause harm to cats which is obviously something that is important. In addition to the products, we have prepared a buyers guide with useful information on how to select the best cat repeller. 

Short on time? ​we think the Pestbye PB0045X2 Cat Repellers is the best model to try first, its the easiest to setup and has proved effective for most people. It effectively protects ground up to 32ft away using a hyper resonance frequency system, which happens to be the most effective at repelling cats but most people cannot hear the sound. Its integrated PIR motion sensor repels at a decent height and this model is really simple to use compared to other similar models. 

BEST PICK

This will, in turn, allow the unit to dispense ultrasonic waves that will startle the cat and other animals away.

Mini Buyers Guide

A snapshot of things to consider before buying a cat scarer

Shopping for something without some knowledge of it can prove tasking. When shopping for cat repellers, consider the size of your garden and the area you want to keep the cats off.

Secondly, you need to consider which of the cat repellent models will work best for you. Some may like using ultrasonic models that work well on lawns as they can cover such a large area and others may be drawn to simpler methods like prickle stops which work well if you want to protect flower beds.

Another good choice are repellents such as silent roar which can easily be scattered around plants. If you have a tall fence which the cats have to jump up onto from a height, the fence wall spikes work very well too.

Usually a combination of 2 or 3 can work very well, for example, using an ultra sonic repeller or water sprinkler repeller to protect your lawn as these cover large areas and then combining this by scattering silent roar pellets around your beds or borders. By using 2 or 3 different methods at once this has proven to work well time and time again. Another tips is to move the sonic repellers or water sprinklers around every few days as cats do learn how to avoid the sensors if left in one place.

There are more factors to consider and you will find them in the buying guide below.

RUNNER-UP

The shots of water that are expelled from the repeller are enough to send cats running because we all know they don’t like getting wet so this is highly effective.

The shots of water that are expelled from the repeller are enough to send cats running because we all know they don’t like getting wet so this is highly effective. The cat repeller has the ability to cover an area of 100 sqm so will protect large lawns and borders, the only downfall is that you have to connect it to a hose which may be a deal breaker for some. Other than that, it is a dependable model that relies on sensors to pick up motion. You may have a few laughs seeing the animals scramble away when the water shot get to them. Just remember to move it around now and again so the cats don't learn how to avoid the sensor.

If you have a large area to protect such as a lawn, this would be our first recommendation.

Buyers Guide

There are many ways to deter cats from using your garden as a toilet. However, some methods are better than others. Some people prefer to use methods that won't harm the animals in any way and others prefer more drastic measures which we wouldn't condone.

Regardless, the best cat repeller has to accomplish the task at hand. Let us look at the different types of cat repelling ways available.

Audio repellents (Ultrasonic)

Audio repellents usually rely on ultrasonic sound waves to scare the animal away. Cats have more sensitive ears designed to hear mice etc and therefore, they are able to pick up sounds that are not audible to the human ear. By emitting the high-pitched ultrasonic sound wave, it irritates their ears so they don't return the area. The intensity of the sound wave matters if you are trying not to harm animals like pigs and dogs.  Choose a range that will keep the animal away without blowing its ear off.

You have the choice to select the power source you want to use. Battery-powered models are convenient but they tend to lack battery level indicators. Solar panels are ideal if you do not want to save on new batteries or recharging but they have there limitations so they still need to be recharged just not as often.

Sprays

There are chemicals used to keep animals from taking over your garden. These chemicals may include odours like lemon/lavender that cats do not like. Additionally, chemicals such as aluminium sulphate are common. They remove a pungent smell that animals cannot stand or won't dig where they have been applied. These sprays are only temporary and therefore, they will need to be reapplied often. The good news is that they are not expensive and they do not harm the animals.

Sprinklers

There are cat repellents that use water to effectively get rid of the animal. They also have motion sensors that pick up any movements and release a shot of water in the direction of the animal. These come with height and range adjustable settings. You have the freedom to select how much further the water can travel.

Cayenne

Cayenne is one of those peppers you do not mess with. Once it penetrates your nose, you will be sneezing and in tears. For cats, this works also as they do not like the smell or the spiciness of the pepper. All you have to do is sprinkle it in the required area and let the cats come to discover it. They will be sure to think twice before returning.

Pellets

There are options to seek crystal/ pellets or some type of gel-like substance that contains methyl nonyl ketone. Cats do not like this stuff because of the foul smell. You may find others enriched by animal pee or dung to make the smell even stronger.

Spikes

Spikes will cost you but if you have unprotected walls and even window sills, they can be very effective. These strips come with a form of adhesive or they can be screwed in to stay in position.

Spikes are tricky though because you have to place them right. You can’t place them in areas where the cat will be able to walk over them. You have to place it in a position that when the cat jumps, the impact forces the spikes to pole the tough pores and cause discomfort without bleeding.

Plants

If all is lost, plants could make the best cat repeller if you have the time engage in such. Cats do not appreciate lavender, lemon thyme, citrus plants, and rosemary among other plants, not forgetting the scary cat plant. You can plant these in your garden as long as they do not affect the other plants in the garden.

Factors to consider when buying a cate repellent

Coverage

You want to buy a cat repellent that covers your garden well. You don’t want to have loopholes where the cats can come through and soil the garden. Whichever method it is, make sure that it is effective depending on the size of your garden. You can even choose to buy several units in order to provide optimal coverage.

Animal protection 

Animals share this planet with us and there is no point in being too drastic. Choose methods that are humane. Choose methods that won’t blind, bleed or expose the animals to toxic chemicals. The point is to deter the animals from being in your garden rather than harm them.

Money-back guarantee

Maybe the product is not what you thought it would be and you want to return it. That is why products that offer money-back guarantees make sense. If you are not sure about a product before purchase, look for a brand that offers money-back guarantees like the Pestbye Sonic Cat Repellers. You may be charged a small postage fee but at least you don’t get stuck with unsatisfying products.

Weatherproof quality

Because these are basically outdoor products, there is only one way to go. Seek products made from durable materials that can survive days of sun, rain, and snow. That requires them to have a high 4PX rating and solid construction to weather out storms if need be.

Other advantages of using cat repellents

  • They save you the time, energy and frustration of chasing the cats physically.
  • Most of them are harmless to the animals and therefore, more humane.
  • Because there are too many options, you do not have to engage with harmful chemicals that might affect your health.
  • Some of the cat repellents double up as manure. Your plants are protected and nourished at the same time.
  • They do not need complex installation processes. They are very easy to engage as they have simple buttons and dials.
  • Some of these devices repel more than cats, you can also keep dogs, rabbits, foxes ad mice at bay.

Our Final Conclusion

It is not going to be a smooth walk in the park dealing with our feline friends. It may take a while before you find a method that works for the type of cats you have around your residence. If you have live around smart cats then you may have to combine some of these methods to create the best cat repeller for your garden as they soon work out how to avoid cat repellers.
