Peppermint oil has many uses: for flavor in desserts and candies; as a pesticide (effective against ants, spiders, and rodents); as a massage oil; and in diffusers. However…
Is peppermint essential oil safe for cats?
Answer: No.
Do not allow your cats to swallow or inhale peppermint oil (that means don’t let them drink it or put it in a diffuser near them).
Why is peppermint oil toxic to cats?
Peppermint oil contains compounds like menthol and pulegone, which cats cannot metabolize effectively due to their liver’s inability to produce certain enzymes. This can lead to a toxic buildup in their system, potentially causing serious health issues such as liver damage, respiratory distress, or even neurological problems. Cats are particularly sensitive to essential oils, and peppermint oil is no exception.
If your cat has been exposed to peppermint oil, watch for symptoms like drooling, vomiting, difficulty breathing, or lethargy. Contact your veterinarian immediately if you notice any of these signs.
Note that the menthol in peppermint oil can also cause side effects for small children and babies.
Is diluted peppermint oil safe for cats?
No. Cats can still absorb the toxic elements through their skin or by inhaling the scent.
