Best Cat Scarer & Cat Scarers Review Guide (UK)


For some, cats are a lovable pet who can bring much joy to a garden. But for others, cats can cause an inconvenience to gardeners. Whether it is bothering flower beds, scaring rabbits and livestock, or damaging garden furniture, there are many reasons why someone would want to keep the neighbour’s cats out of their garden.

A scarer is often the best way to go about this, as they are able to provide you with a safe and humane way of keeping them off your property. They are not harmful to the cat, and merely present themselves as a territorial figure that doesn’t want anyone else on their lawn. It’s a superb option to go for, and one that could keep your garden feline free.

However, with so many different types of scarers on the market, it can be hard to know which are humane and useful. In order to help you find the best cat scarers, we have put this guide together, compiling all of the relevant scarer reviews in one place, so you can find one that works for you.

3. PestBye Primrose

Best Value Cat Scarer 

There’s nothing better than an effective scarer for a reasonable price, and that’s where we come in with a truly superb offer.

The Good

With an adjustable range of sensitivity settings, this motion sensor scarer is the perfect thing for people who want to make sure the cat learns a lesson.

When it detects motion, a small jet of water is sprayed, not only making the cat wet but also creating a hissing noise to deter the cat from disturbing your garden.

However, it still remains a very human model to use and does not hurt the cat.

The motion sensor and spray can cover up to 10 metres of ground, and will only activate when triggered, conserving the amount of water used.

This scarer, despite the water jet, will not harm the cat in any way. Rather, it will give it a physical deterrent to dissuade it from your garden, rather than a non-obtrusive one.

The Not So Good

Some customers have noticed that the water doesn’t spray with enough force to deter the cat. However, this problem can be amended by adjusting the amount of water pressure placed into the scarer.

Features - 
  • Brand : PestBye
  • Distance Up To : 10M
  • Power: Requires 4 x AA Batteries
  • Area Covered: 120 degree arc

This scarer is extremely effective, especially at its affordable price. By using a spray rather than sound, it not only will affect all types of cat, but will also give the cat an unharmful threat to avoid.

Better yet, some people have also placed these sprays near their flowerbed. It dissuades cats, and can give a little watering to your plants, at the exact same time.

As we mentioned before, it is important to note that it is still a humane way to keep cats off your lawn, and they tend to learn very quickly.

Buyer Guide

How To Buy The Best Cat Scarer

Are your local neighbourhood cats ruining your garden? Have you been finding feline droppings in various spots? Here is an expert guide to help you decide how to buy the best cat scarer for you.

A well-maintained garden is a source of pride and joy for any avid gardener, but there is one thing that can ruin any lawn; cat droppings. Once a neighbourhood cat has chosen a spot in your garden to do their business, it can be a pain trying to get them to leave. Before buying a scarer, ask yourself these questions:

  • What are the problem spots? Where do you most often find cat faeces in the garden?
  • What is your budget? Do you want to buy a high-end product or perhaps something simple and easy on your wallet?
  • How do you feel about installing a device? Would you prefer an alternative method?

This guide will help you decide what scarer is best for you.

Before you begin

Before spending money on a scarer, you may want to try using some alternative methods to see if they ward off the troublemakers.

  • Pick up and dispose of any faeces as soon as possible. Leaving them could damage the lawn.
  • If the spot is on a solid surface, try washing the area with soap and water to minimise the smell.
  • Cats dislike citrus smells; leaving lemon and orange peels in hotspots may deter them from coming back.
  • If you do catch a cat in the act, do not scare it away. Pick it up safely and gently place it

What types of scarer are available?

Sound devices

One of the safest and most effective cat repellents, sound devices release a high-pitched noise that cannot be heard by humans. This high-pitched noise is incredibly unpleasant for cats and encourages them to stay away. Sound devices can be either battery or solar powered and some are triggered by movement or heat signatures. Make sure you buy one with a power meter display as not all of them have one, making it difficult to know if they are operating or not.

Cayenne pepper

An old housewives’ trick, cayenne peppers are too spicy for cats. Smelling it or getting it on their fur can make cats feel agitated without harming them. Scatter it in and around the area where the cats have done their business and it should work. This remedy works best for small-scale cat infestations. If you have a more serious issue at hand, getting manufactured products may be best for you.

Cat repellent sprays

An effective solution to cat infestations is cat repellent sprays. These sprays often contain aluminium sulphate, a natural deterrent for cats and other animals like rats, dogs, and birds. It may take testing a few different ones before you find the most effective one for you. One bottle usually has enough fluid to cover a small garden for a year. Cat repellent sprays have a strong smell and may deter wildlife you like from entering your garden.

Chicken wire

Placing chicken wire over or around specific hotspots in your garden can be effective as cats hate walking on it. Placing a tilted border of chicken wire around the garden or commonly used spot should deter cats from continuing.


An intense but effective solution could be to place metal or plastic spikes on your fences. While it can be expensive, it can be effective at both removing cats from your garden and updating its look. If you do install spikes on your fences, make sure to place them close together to ensure there is little room to walk along them.

Granules or crystals

Granules and crystals are biodegradable pellets which have a distinct odour. Scattering them in flower beds and problem areas can prevent cats from disturbing the soil. It can be difficult knowing how much to buy in order to cover your entire garden. However, there are large amounts available with set quantities per square foot.

Automatic sprinklers

Available in both indoor and outdoor models, automatic sprinklers detect movement or heat signatures. Once a cat gets close to the sprinkler, it sprays water at them. Many gardeners who install sprinklers can often remove them after a few weeks of continuous use.


There are certain plants that cats dislike the smell of. Some cat repellents plants include:

  • Rue
  • Lavender
  • Pennyroyal
  • Lemon thyme
  • Coleus canina

As a bonus, these plants will attract pollinators and help repel other pests.

How much should I spend on a scarer?

Cat scarers seem like an odd investment, but your health and your garden will thank you for it. Most cat scarers are priced between £5 and £35. Some items, such as dish soap, chicken wire and cayenne pepper may already be in your home. Sound devices and automatic sprinklers are often more expensive options but can be effective at dealing with feline infestations.
