Citrus: orange, lemon, lime, and grapefruit Citrus smells are widely reported as being repugnant to cats. You can use this to your advantage by throwing orange peels around your garden to keep cats away or spritzing a citrus scent on indoor fabric that you don't want your cat scratching up.
This includes oranges, limes, and lemons. The citrusy smell of lemons, limes, and oranges is often associated with freshness and alertness. However, for a cat, it is quite unpleasant. Most cats are put off by strong citrus scents, especially from the peels of the fruit and fragrances.
