    You can use the urine of animals like mountain lions, coyotes, or foxes from online retailers. [3] Basically, you spray the urine, creating a border around your property. [4] It's better to use these sprays to create a border around your yard rather than your entryway.
    • The smell of these types of urine are going to be very strong, which is why you should only use them around the yard. You shouldn't spray these urine right by your door, as it will be unpleasant when you're going in and out. Even when you spray them in the yard, you're going to be able to smell them. [5]

    These types of doors involve your pet having an electronic signal of some sort that opens the door for them. The signal can come from a tag on the pet's collar, but some pet doors also use the microchip that many pet owners embed in the pet for identification purposes.
    • When an unwanted cat approaches, she won't have the appropriate signal, so the door will not open for her.

    Similarly, if you feed cats, they will hang around. If you really want to feed strays, do it in an area away from your entrance, and create a barrier with scent around your door. That way, the cats will stay in their area and not in your home.

    Try catnip . If your main goal is to keep the cat out of the house, try making a part of your garden attractive to cats. For instance, you could plant catnip or cat mint, both plants that cats love. Pick a corner that's out of the way. Be aware, though, that this method could draw more strays to your yard.
    • Honeysuckle is also a cat-friendly option. [13]

    Cats also like sleeping on sand, so you could make a bed of sand near the catnip. Cats will be drawn over to take a nap.
    • Some cats may see this area as an opportunity to use the bathroom, so you may find yourself cleaning up after them.

    It's no secret that cats like to watch birds. Therefore, if you have your bird feeder up near the house, you're likely to have cats around. By moving the feeders out into the yard, you at least move them away from your door.

    There are some natural repellents, but the most efficient one depends on the cat, as some cats are more bothered by some than by others. Citronella, citrus, and coffee grounds are some good options.

    You can buy products that are targeted for repelling outdoor cats. Try keeping food out of your yard and making sure your garbage is secure so that the outdoor cats won't find anything interesting in your yard. Of course, you want to be careful to make sure you're not scaring your cat off from your yard as well.

    Expert Answer
    You can buy pet doors that are microchip enabled, so they only open for your pet. Or you can get ones that open with a magnetic door that only opens for your pet. You can also go full cat-proof with a fence, if that's appropriate.

      About This Article

      Article Summary X

      To keep unwanted cats out of the house, try spraying lemon juice outside your door, because most cats don’t like the smell of citrus. Alternatively, you can sprinkle cayenne pepper or coffee grounds outside your entrance, which can also serve as a deterrent. Additionally, consider placing certain plants near your door, such as lavender or penny royal, since the smell of these plants can repel cats. If none of these methods work, try buying a commercial cat repellent spray from a pet store to keep cats away. For more tips from our Veterinary co-author, like how to use catnip to keep unwanted cats out of the house, read on!
