Is Peppermint Oil Harmful to Cats?

Peppermint oil is harmful to cats, as are other peppermint products. Peppermint oil has been known to send some cats to the hospital, according to "Natural Remedies for Dogs and Cats" by C.J. Puotinen.

  1. Side Effects

    • According to the American Society for the Prevention of Cruelty to Animals (ASPCA), cats are highly sensitive to peppermint oil as compared to other animals and other peppermint products. Peppermint oil can result in upset stomach, central nervous system dysfunction and liver damage.

    Significance

    • Cats are physiologically different from other house pets. Dogs may be exposed to peppermint oil as a form of aromatherapy for emotional or behavioral problems. Dogs may also be drink peppermint tea for an upset stomach, according to Dr. Susan Pitcairn. Do not use either method for your cat.

    Considerations

    • Peppermint oil is not the only form of peppermint harmful to cats. All peppermint products should be avoided, including any part of the plant itself.

    Solution

    • The ASPCA recommends removing any household peppermint plants or other products from the reach of the cat. Substitutes for aromatherapy oils called hydrosols are available that are safe for cats and kittens. Hydrosols are the sweet-smelling waters that are emitted during the making of essential oils.

    Warning

    • Do not apply any hydrosol that smells strange or contains residue to a cat.
