Best Cat Deterrent UK

Cats are gorgeous animals. Feline, graceful, and highly independent, are just some of the adjectives used to describe them. Some negative ones are flighty, un-trainable, and vicious. However, no matter how beautiful an animal is, it does need to relieve itself every now and then. This can create quite a mess, especially when a cat comes trooping into your garden or lawn to poop and pee.

Going to the toilet in your garden is sure to upset and dismay you since you would have to clean up after it. Apart from the mess that cats create after they’re done, the resultant smell is nauseating.

Many people believe that faeces of any kind can provide manure and nutrition to plants. This widespread belief is not valid for cat refuse. Cat faeces is not a good fertilizer and can harm your plants instead of helping them grow.

Cats also return to a region based on their own smell. In this manner, a cat will keep coming back to the same spot, again and again, to relieve itself irrespective of how many times you try shooing it away.

Why do Cats Like to Use the Garden?

Domestic cats, like all creatures in the large cat family, use their sense of smell to track and locate objects and things. Their sense of smell is so acute that it blindly guides them to places they have been before. Due to this extra keen sense of smell, the cat will keep coming back to the same place again and again.

Cats do not prefer fresh smells like humans do. Instead, they prefer the scent of their own bodily refuse instead of a clean smelling space. They do not like their smells being removed or cleaned after them, and this causes a renewed sense of urgency to mark their property or territory again. Marking a property is also their way of ensuring other cats and animals know that this location is taken and is not to be used.

1   Get Off Cat and Dog Repellant Crystals

KEMEI Men's Cordless Hair Clippers

These crystals have to be mixed into the soil and flowering beds to ensure that cats and dogs do not venture on to the area. Extremely cost effective, these crystals and man-made, so should not be used near water bodies like ponds and lakes. The crystals are incredibly harmful to fish and can contaminate the water.

4   Defenders Prickle Strip Dig Stopper

ELEHOT Hair Clippers

The Prickle Strip prevents animals like foxes, cats, dogs, squirrels, rabbits, and other wildlife from digging into your garden or lawn. Cats have a habit of covering up their refuse behind them.

The Defenders Prickle Strip Dig Stopper keeps pets off the flowerbeds, soil, seedbeds, containers, pots, vegetable patches, and other areas that have been planted.

If animals try to dig, they feel a tingling on the pads of their feet. This feeling does not hurt, but it deters them from revisiting the same place to do their business.

5   Silent Roar Cat Repellant and Fertilizer

Wahl Colour Pro Cordless Hair Clipper

The Silent Roar Cat Repellant and Fertilizer is actually quite an ingenious way of keeping domestic cats away from your garden and lawn. The Silent Roar, 2 kg packet, is made up of small fertilizer pellets that have been soaked in lion dung and then dried to provide manure and nutrition to plants. The reason why this is such a fantastic deterrent is that cats use their sense of smell to guide them. Suddenly their senses let them know that a lion has moved into their area.

Since cats are wary of others in the feline family, the smell of the lion dung causes havoc to their mind. They quickly learn to stay away from the supposed territory of the large predator (lion). Thankfully, the human sense of smell is not as advanced as animals, and we do not smell anything unnatural. To use the Silent Roar Fertilizer and Cat Repellant, just spread the pellets around your property and in flower beds.

Key features:
  • Acts as fertilizer
  • Naturally deters cats
  • Humans cannot perceive the smell the lion dung

Buyers Guide for Cat Repellents

Cats are gorgeous animals. Some of the adjectives used to describe cats are graceful, beautiful, and highly independent. However, there are even some negative thoughts used for cats as untrainable, vicious, and even flighty. No matter how cute your cat is, there is an excellent chance you will get annoyed occasionally.

Since cats are usually quite clean, you might not know where they go off to do their business. However, when cats pee and poop around the house, the resultant smell can be fetid and nauseating. Cats are incredibly territorial, and they usually continue marking their territory by conducting their daily ablutions in the same place as before.

It is a well-known fact that cat faeces are not suitable as a fertilizer. What this means is that when cats venture into your lawn or garden, they are decreasing the nutritional content of your garden instead of reviving it. Cat faeces tend to harm plants and reduce the growth rate and eventually kill them. Such situations make it essential for you to use cat repellant so that cats do not spoil your garden soil.

How to Choose the Best Cat Repellant?

Unlike humans, cats prefer to frequent areas where they can scent their bodily refuse. They do not like smells that are removed or cleaned. This point is possibly the most important one if you want to discourage a cat from coming to your property. Additionally, you can also mask the scent of the cat with another animal to deter further occurrences.

Electronic Repellant

You can easily use an electronic cat repellant either inside or outside the house. It works on infrared and ultrasonic wave systems. The units that you find in an electronic cat repellant will help locate cats by transmitting an ultrasonic sound plus flashing LED lights. The lights and waves work like an alarm to deter cats from dumping their faeces in your garden.

The most beneficial part about using an electronic cat repellant is that the sound produced is inaudible to humans, but works as a threat for cats. The high-pitched sound plus bright light emitted from the electronic motion detector frightens the can and helps them avoid your property in the future.

Consider Odorless Cat Repellent Sprays

With the use of a cat repellent spray, you can stop cats from misbehaving at your home and from ruining your furniture. Cat repellent sprays can be used outdoors and indoors to train cats to curb aggressive or destructive behaviour. When you spray the repellant over an area, your cat gets an unpleasant smell and starts avoiding that area. Doing this helps prevent cats from peeing and clawing in those areas. Cat repellant sprays may also be used in the gardens but may run out as you water your plants. For the duration that the spray works, cats will stop digging the soil, preying on birds and mice, and stop scratching your trees.

Cat repellant sprays are odourless for humans, and so can be used around the house without any discomfort. It is easy and quick to use, and if sprayed indoors, the effect usually lasts for a week.

Whenever you purchase a new product, you have to ensure it is durable. The same goes for cat repellants. If the repellant runs out, and stop being useful, it is a waste of time and money. You would have to find other ways to deter cats from coming on to your property and spoiling your things. Since cats have acute olfactory senses, they can quickly recognize previously frequented places based on their sense of smell alone. If you mask their scent with something else, you can deter them from returning. However, if the repellant you have used is useful only for a short span, and the scent of the cat returns too quickly, the cat may come back. 


Cat Repellent Mats

Cat repellant mats are soon becoming quite popular since they make a sound that scares the cat. Anytime the cat steps on it, a sound is emitted that makes the nosy feline run away. Cat repellant mats come in a variety of assorted sizes. You can install mats anywhere where you feel the need to protect your property from cats. Plastic strips in the cat repellent mat will not harm the cats, and it is an effective way to discourage them from digging or scratching. You can line your garden beds and lawn borders with these repellant mats.
