While cats make great pets and companions, it is hard to deny that they can be quite frustrating. Nobody knows this more than gardeners, who are often at the mercy of stray and outdoor cats that use their outdoor space as their personal toilet. To avoid such problems, you need the best cat repellent, which can be easier said than done as there are so many products to choose from, and not all are guaranteed to work. To help you know what to look for, we’ve created a handy buying guide that covers all the info you need to know to find the best cat repellents.

What are cat repellents?

Cat repellent is a collective term for devices and substances that are used to deter cats from entering a space, or to scare them off should they enter. This is most commonly used in gardens, where cats often defecate, dig, and generally be a nuisance. There are various types of cat repellents, including electronic devices like ultrasonic sound emitters and water sprays, substances like repellent powders and sprays, and objects like wall spikes and chicken wire, and even natural repellents like certain plants that cats dislike.

Why should you buy a good cat repellent?

There are fewer things more frustrating than having to clean up cat faeces in your garden. It’s something that many people deal with, as cats often return to the same area to do their business. Moreover, unwanted cats can also be destructive, digging up plants and flowers, while they may also fight with other cats in territorial disputes.

To avoid all these problems, you need the best cat repellent. These can be used to scare cats from ever entering your garden, while also chasing off any that are brave enough to enter. Most are affordable and easy to use, making it a great investment for anyone that does not want unwelcomed cats on their property.

Here are some things to consider when buying the best cat repellents:

  • Repellent Type: There are multiple types of repellents available, any of which may be suitable for your needs. Some of these are thought to be more effective than others, such as ultrasonic sound emitters, although many swear that sprays and powders work just as well. You may need to try several repellents to see what works best - you can find more detail about these in the section below.
  • Garden Size: Certain cat repellents, such as ultrasonic repellents and water sprays, have a limited range, so you need to consider the garden size to make sure it is effective. Most use infrared sensors with a set range, so if using this type of repellent make sure it has enough range to cover your entire garden or at least the area that the cat is entering from.
  • Durability: Some cat repellents are left outside indefinitely, so always consider their durability to ensure it lasts. Water sprays, ultrasonic sound emitters, and wall spikes may deteriorate over time and need to be replaced, so look for those that are built from durable materials and are weather resistant.

What is the best kind of cat repellent in Australia?

Here are some of the best-selling cat repellents available to buy:

  • Ultrasonic Cat Repellents: This solar-powered device is stuck into the ground, letting off an ultrasonic alarm whenever the sensor is triggered by a passing cat. The noise it produces is horrible for cats, usually causing them to flee. Many view this as the best and most effective cat repellent.
  • Water-based Cat Repellents: Like an ultrasonic repellent, water sprays are inserted into the ground and activate when a sensor is triggered by a cat, but instead of ultrasonic soundwaves it shoots a jet of water to scare off the cat.
  • Wall Spikes: These plastic spikes are installed on top of walls and fences that cats use to enter the garden. While not harmful, the spikes do make it difficult for the cat to enter your property.
  • Cat Repellent Sprays: These cat repellents are easy to use, being placed in problem areas to deter cats from digging or defecating. They work by producing an unpleasant perfume that cats hate.
