How to Make Sour Spray

Perhaps your cat's chewing on your African violet, or your dog's shown an interest in your lamp cord. Inappropriate chewing is not only annoying, it's potentially dangerous. Spraying the object of your pet's attention with bitter or sour spray can be an effective deterrent. If you don't want to buy sour spray, you can mix up a batch of your own with some common cooking ingredients.

Sour Spray From Your Pantry

Like it or not, there's no denying vinegar will make your lips curl. Vinegar will have the same effect on your dog or cat, who probably won't like it. Mixing 2 cups of apple cider vinegar with a cup of white vinegar in a spray bottle makes a safe but effective sour spray. If you don't have cider vinegar, try substituting 2 cups of lemon juice. Dogs and cats don't care for the scent or taste of citrus, so your shoes will be safe with this concoction. If you don't have vinegar on hand, try mixing 1 part of cayenne pepper to 10 parts water for a spicy deterrent. Though cayenne uses spice instead of sour, its irritating properties can be an effective warning. More isn't better in this case; too much cayenne can irritate your pet's sensitive nose. He needs just enough to irritate his nose and throat a little so he avoids the potential object of his affection. If you're trying to keep your pet from licking a wound or some other part of his body, talk to your vet about a deterrent that won't irritate his skin or fur.
