Consulted references classify the plant as toxic or irritating for that pet type.
Vomiting, decreased appetite, and potential lethargy.
Ingestion typically results in mild to moderate gastrointestinal upset. Please contact your veterinarian if your cat consumes a significant amount of the plant.
Move the cat away from the plant and gently wipe out any plant matter from the mouth. If essential oil got on the fur or skin, wash it off with a mild dish soap to prevent further absorption. Do not induce vomiting unless instructed by a veterinarian or poison control.
Most common signs after chewing the plant: nausea, vomiting, and inappetence. Watch for drooling, lethargy, or refusal of food in the hours after exposure. Concentrated lavender essential oil can additionally cause tremors, wobbliness (ataxia), and respiratory irritation in cats.
GI signs from chewing the plant typically appear within a few hours and resolve in 24–48 hours with supportive care. Essential-oil exposure can cause signs that take 3–7 days to fully resolve.
Call a vet or ASPCA Poison Control (888-426-4435) if your cat has chewed more than a leaf or two, has been exposed to lavender essential oil or potpourri, or shows persistent vomiting, drooling, lethargy, tremors, or stops eating.
Cats: lavender is listed by ASPCA as toxic, with linalool and linalyl acetate as the toxic principles. Cats are particularly sensitive because they lack the liver enzymes needed to efficiently clear these compounds, so concentrated exposures (essential oil, dried potpourri) deserve more concern than a brushed-off leaf.
