Cats are more sensitive to scents than humans, so essential oils with strong odors, such as citrus and lavender, can help repel them. You can substitute lime, peppermint, and/or eucalyptus for the lemon, wild orange, and lavender if you prefer. It’s important to use a glass bottle for the spray because essential oils degrade more easily in a plastic bottle.

It isn’t necessary to use filtered or purified water for the spray. Regular tap water works fine.

Be careful spraying the repellent on carpeting, curtains, or other fabrics because the oils may stain the material. Test it on an inconspicuous spot on the fabric to ensure that the spray won’t damage it.

Use white vinegar for the spray. You can use tap, filtered, purified, or bottled water for the repellent. You can use either a plastic or glass spray bottle for repellent.

Any type of hand soap will work for the repellent, but it’s best to use a clear formula.

You can use the repellent to keep cats away from both indoor and outdoor locations.

Because you’re boiling it, tap water is fine for the repellent.

Cat dislike citrus scents, so any combination of orange, lemon, lime, and/or tangerine peels that totals a cup (96 g) will work for the repellent. If the mixture begins to boil again, lower the heat.

If the citrus peels are in large chunks, you can strain them out of the mixture so it’s easier to pour into the bottle.

You can substitute lime or orange juice for the lemon, but be sure to use freshly squeezed juice. You can use any type of clear dish soap, but a lemon-scented formula works best because cats don’t like the citrus scent.

To be safe, it’s best to test the repellent on an inconspicuous spot on fabric-covered items to ensure that the ingredients won’t damage the material.

Tap, filtered, purified, and bottled water will all work for the repellent. Using a glass spray bottle helps keep the repellent effect because the oil is more likely to break down in a plastic container.

Like citrus and other essential oils, citronella oil has an extremely strong odor that repels cats. It is also effective in keeping insects away.

If you are using the citronella repellent in an area where cats have gone to the bathroom, it’s important to clean the spot thoroughly before applying the repellent.

You can substitute cayenne pepper for the black if you prefer.

You can substitute ⅛ teaspoon (½ g) of garlic powder for the clove. Lime, wild orange, or grapefruit essential oil will work in place of the lemon.

Tap water will work well for the repellent.

You can also use the repellent to keep cats away from indoor plants.
