Is Lavender oil dangerous for cats?

No — dangerous

No. Lavender essential oil is toxic to cats. (Fresh or dried lavender plants are much less of a concern, though best avoided.)

If your cat has just eaten lavender oil

  1. Move to fresh air if exposure was via a diffuser.
  2. Wash any oil from fur.
  3. Call your vet.

What's the full picture?

Concentrated lavender essential oil — in diffusers, sprays, laundry products, and some 'calming' pet products — is toxic to cats. The marketing of lavender as a calming scent for anxious pets is misleading and genuinely dangerous for cats.

Fresh or dried lavender plants are much lower risk, though a cat eating a lot of plant material can still have stomach upset.

Symptoms to watch for

0–4 hours
Drooling, vomiting, wobbliness.
4–24 hours
Persistent lethargy in significant exposures.

About this guidance

Every entry on this site is compiled from published UK veterinary toxicology sources — International Cat Care, Veterinary Poisons Information Service (VPIS) references, RCVS-registered practice materials, and peer-reviewed feline medicine literature. Where the evidence is mixed, we err on the cautious side because cats are unusually sensitive to many common substances that are harmless to humans and even to dogs.

This is general information written for UK cat owners. It is not personalised veterinary advice for your specific cat, their age, weight, medical history, or the exact exposure you're dealing with. If your cat has eaten something or is unwell, call your vet first. The Animal PoisonLine on 01202 509000 is available 24/7 for a small fee and can tell you whether an emergency visit is needed.

Entries are reviewed and updated as new research emerges. Spotted an error? Let us know — corrections are investigated and applied within 24 hours. For more context on how we work, see about and our full disclaimer.
