Which Is The Best Cat Scarer On The UK Market?

As a cat person, I’ll be the first to admit that cats are lovable pets and great companions. However, there’s no shortage of occasions where these cute felines turn into a massive nuisance. This especially applies to homeowners with well-manicured landscapes and levelled gardens.

Looking at my two energy-packed cats, their list of transgressions is endless. I mean, they constantly dig up my plants and new flower beds pooping all over the place.

As if that wasn’t enough, they relieve themselves everywhere creating discoloured patches all over the lawn. But just when you think you have them potty trained, they go ahead and pull a fast one on you. I can’t even physically count the number of times they have teased dogs and brought the fight right to my lawn and garden.

Over time, I did learn that cats will be cats. So whether you’re looking to keep your beloved cats from your flowerbed or repel feral cats, dogs, foxes, and other animals, there’s finally a safe and effective way to do it.

That’s right; with the best cat scarer, you can keep your pets and neighbouring animals in line in a friendly way.

Today, there are all sorts of cat repellents on the market. In my search, I discovered all kinds of innovative cat scarers. From safe water sprays to state of the art ultrasonic deterrents and motion activated sensors, there are many ways to go about it depending on your overall goal.

Top Rated Cat Scarers In The UK

Below is a catalogue of the most effective deterrents and best cat scarer(s) that work on felines as well as other animals.

1. Primrose PestBye Ultrasonic Motion Activated Cat Repellent


When it comes to pet/pest repellents, Primrose is hands down one of the best brands for the job. They boast of what is perhaps the most advanced cat scarer of all time. The Primrose PestBye Ultrasonic Motion Activated Cat Repellent is designed to let out extremely loud noises at frequencies that cats can hear, but humans can’t.

These frequencies are also effective against foxes, dogs, and other pesky animals. The scarer from Primrose comes complete with infra-red motion sensors that activate the device whenever a warm body enters the controlled area. This advanced cat repellent requires four AA batteries that can last up to 4 months even with over 10 activations a day. And as a bonus, the units are easy to install since all you have to do is push them into the ground with provided stakes.

What I like about it:

  • Comes in a set of 2
  • Contains infrared motion sensors
  • Easy to install

2. Voss Sonic Cat and Pest Scarer


When Voss branded their newest pest scarer as simply effective, they got the description head-on. The Voss Sonic Cat and Pest Scarer comes in a dark green exterior so that it blends seamlessly with your lawn and garden. But that’s not where the eco-friendliness ends. The manufacturer made the repeller solar powered so it charges while still working out in the garden.

Like the first cat scarer, the Voss Sonic Cat and Pest Scarer also repels unwanted cats, pests, and rodents by using a patented adjustable ultrasonic sound system. This allows users to choose a frequency that works on different types or species of animals. So all you have to do is place the scarer, select a frequency and watch as it clears pests and animals from a 22-foot range.

What I like about it:

  • Dark green colour for camouflage blending
  • Allows users to set the desired frequency
  • Can be battery operated or solar powered

3. Primrose PestBye Jet Spray Animal Repeller


If you’re looking for a more humane way to scare cats and other animals from your garden, Primrose also has another trick up their sleeve. But instead of ultrasonic sound waves, the repeller makes use of good old H2O. The Primrose PestBye Jet Spray Animal Repeller is strong, robust, practical and very effective if I might add.

The scarer is primed to give animals short sprays of water whenever they pass in front of the motion sensor. It works on cats, dogs, squirrels, and even herons. The Primrose PestBye Jet Spray Animal Repeller covers an area of 100sq metres and fires a 5-second burst of water when triggered. This jet encompasses a 10m range with a 120-degree water arc that resets after every activation.

What I like about it:

  • Makes use of water sprays
  • Adjustable range of sensitivity with motion sensor
  • Wider coverage range

4. PestExpel Humane Animal Deterrent Spikes


Are you looking for a more affordable, low tech way to keep a myriad of animals away from your lawn? Well, PestExpel has the perfect solution for your low tech needs. I’m talking about the PestExpel Humane Animal Deterrent Spikes that provide a safer and effective way to mark your territory.

This scarer comprises of 2 strips that each measure 43 by 14 by 2.5 cm. Each strip is made from interlocking flexible plastic with mini spikes that feel quite uncomfortable to the feet and paws of animals. However, it doesn’t hurt the animals in any way; just really annoys them. These strips are discreet, durable, can be cut to shape and stand up to even the toughest elements.

What I like about it:

  • Flexible spikes can be used to set up a perimeter
  • Discreet and incredibly weatherproof
  • Easy to install and put away

5. Silentroar Silent Roar Nitrogen Based Fertilizer


As promised, this segment aims at shedding light on all the different types of cat scarers out there. Seeing that gardens and flower beds are literally the playgrounds and potties for cats and most animals, why not kill two birds with one stone so to speak.

By using the Silentroar Silent Roar Nitrogen Based Fertilizer, you get the benefits of added nutrients to the soil as well as an effective cat deterrent. This fertilizer is actually made from real lion dung to give it the essence of a big cat. Once the fertilizer has been spread all over your garden, it’s safe to say that cats will stay away from lion territory for good.

What I like about it:

  • Actual nitrogen-based fertilizer for your garden
  • Naturally effective cat repellent
  • Single application lasts up to 3 months

Frequently Asked Questions

Q: How to dispose of cat poo in garden?

Cat poop is not a pleasant thing, and unlike horse manure it will not do your garden any good! You can bury the mess, but make sure you do it far away from any prized plants, and bury it very deeply so that the cats don’t come back because of the smell, thinking your garden is now their territory.

You could also try composting the cat poo in your garden, but you should do this separately from your normal compost and not use the resulting compost on your garden for several years – if ever.

Another method is the tried and tested “bag it and bin it”; scoop the poop into a plastic bag – you can either buy bags especially for this purpose or you can use any plastic or paper bag you have lying around – and dispose of it safely in a sealed bin.

Q: How to stop a cat from pooping in the garden?

There are a great many ways you can stop unwanted cat “gifts” from arriving in your garden.

  • Cats like to dig little holes for their poop, so by covering up the fresh soil that they like to dig in, you are removing your garden’s attractiveness as a litter box.
  • Chicken wire. You can lay wire with 1 inch openings over the paths that lead into your garden, and this should deter cats as they don’t like the feeling of the wire under their paws. It also stops them from digging.
  • Cat repellents. You can buy specialist cat deterrents at most hardware stores; things like lion’s poo collected from zoos – the scent of this will send most cats running. Cats also don’t like the smell of citrus, so spreading out orange or lemon peel is a good bet.
  • Plant branches. Placing small branches or twigs in a criss cross pattern across your plant beds should deter cats from walking on the beds.
  • Motion sensors like those in this article. Using either water or ultrasonic sounds, these clever devices should prevent most feline intruders into your garden.
  • Plant Rue. This plant is poisonous to cats, so they will tend to avoid areas it is planted.

Q: How to get rid of cat pee smell in the garden?

If you can spot where the cat is going, you will stand a far better chance of removing the smell of cat pee. They tend to scent mark on vertical surfaces, so the walls of your house or shed are generally the main culprits.

  1. When you have identified the area that smells, rinse it down thoroughly with a hosepipe or watering can, to dilute the urine.
  2. Next, make a solution of 2 parts water and 1 part white vinegar. Shake this together in a spray bottle, and spray it liberally on all the affected surfaces.
  3. You can then use your spray bottle to cover the walls, garden furniture, or whatever else has been scent marked, with a pleasant smelling alternative that cats don’t like, such as lavender, citrus or peppermint oil.

Q: How to stop my cat going into neighbour’s garden?

There is not a lot you can do to stop a cat doing what he wants to do! The best bet, in this situation, is to talk to your neighbour and ask them to discourage the cat by shooing him away, or even providing them with a water pistol so they can squirt water at him to put him off!

Or, you could purchase a cat silhouette to go in their garden, as most cats will not stray into another’s territory.

Your neighbour may be very happy to help with keeping your cat away, so perhaps sharing the cost of a sensor-based cat scaring device may work. If your cat persists in going next door, you may have to sell up and move!
