Step 1
Measure two cups of water into a small saucepan. Add one cup of citrus peels. Choose from orange, lemon, grapefruit, lime or any combination that you find pleasing.
Step 2
Place the pan over high heat and bring the water to a boil. Reduce the heat and allow the mixture to simmer for 15 minutes.
Step 3
Remove the pan from the heat and set it aside to cool. Once the contents have reached room temperature, pour the solution through a coffee filter to remove all of the solid pieces of peel.
Step 4
Add two tbsp. of citrus scented liquid soap and two tbsp. of lemon juice to the water and stir until well blended.
Step 5
Transfer the mixture to a plastic bottle with a spray attachment. Spray any furniture you'd like the cat to stay away from with a liberal coating of the repellent. Additionally, the spray can be used on plants and shrubbery to stop cats from eating them or to establish a chemical perimeter around your garden.
Step 6
Reapply as needed. Outdoor plants will need a new spritz after a rain shower or after routine watering. Indoor surfaces will require an additional application about once every two weeks.
