Is Peppermint Oil Safe for Cats?
No — Peppermint Oil is toxic to cats.
Peppermint oil is toxic to cats because they lack the enzyme needed to metabolize its active compounds, menthol and monoterpenes. Exposure through ingestion, skin contact, or diffusion can cause vomiting, drooling, lethargy, ataxia, and respiratory distress, with possible liver effects. If your cat has been exposed, contact a veterinarian promptly.
