Safety status
What this means for your cat
Garden mint is listed as toxic to cats by the ASPCA, with essential oils as the toxic principle. A leaf or two grazed in the garden usually causes nothing worse than mild GI upset, but cats are unusually sensitive to mint-family essential oils — they lack a key liver enzyme to metabolize them — so concentrated exposures (essential oils, large ingestions of fresh leaves) are riskier for cats than for dogs.
What to watch for
Most common with leaf ingestion: vomiting and diarrhea, especially with larger amounts. Watch additionally for drooling, lethargy, or unsteadiness if your cat got into mint essential oil rather than fresh leaves — those exposures can progress to tremors, low body temperature, or breathing difficulty.
Time window
GI signs from leaf ingestion typically appear within a few hours and resolve in 24–48 hours with supportive care. Essential-oil exposures can cause signs more quickly. ASPCA does not give specific timing for fresh-mint ingestion.
When to call the vet
Call your vet or ASPCA APCC (888-426-4435) if your cat ate a large amount of fresh mint, has repeated vomiting or diarrhea, or got into peppermint or other mint essential oils. A single grazed leaf with no symptoms can usually be watched at home.
