Lemon Oil Cat Repellent. Orange and lemon oil can be utilized for housecleaning purposes. Eucalyptus oil is used as a deterrent for numerous animals, among them fleas, mosquitoes, mice and rats and — and you guessed it — cats.

If you wish, substitute lemongrass oil for citronella oil for a refreshing scent. Replace the lid and shake well. Citrus fruits’ peels such as orange, lemon, and grapefruit are excellent cat repellent.
