Is Lavender Toxic to Cats?
Yes. Lavender (Lavandula spp.) is toxic to cats.
All parts of the lavender plant — the flowers, leaves, stems, and the oil within them — contain compounds that are harmful to cats.
Lavender contains:
- Linalool
- Linalyl acetate
- Terpenes
- Essential oils
Cats lack the liver enzymes needed to metabolize these compounds, causing toxicity buildup.
✔ Toxic Plant?
Yes.
✔ Safe in small amounts?
No. Not recommended.
✔ Most dangerous form?
Lavender essential oil — highly toxic.
Why Is Lavender Toxic to Cats?
Cats cannot break down linalool, a natural compound found in lavender.
Linalool is harmless to humans but toxic to cats because they lack glucuronyl transferase, the enzyme responsible for detoxifying essential oils.
When a cat ingests or inhales lavender, these compounds can cause:
- Liver stress
- Digestive irritation
- Neurological symptoms
- Skin reactions
Essential oils make the toxicity even worse because they contain concentrated levels of linalool.
Forms of Lavender and Their Safety Level
Different lavender products pose different risks. Here’s the breakdown:
❌ Fresh Lavender (flowers, stems, leaves)
Mild to moderate toxicity if eaten.
❌ Dried Lavender
More concentrated — more dangerous.
❌ Lavender Essential Oil
EXTREMELY TOXIC — can poison cats through:
- ingestion
- skin contact
- inhalation (diffusers)
❌ Lavender Candles, Sprays, Incense
Often contain essential oils → unsafe.
❌ Lavender Tea
Unsafe — contains extracted oils.
❌ Lavender Oil in Beauty Products
Lotions, creams, balms — toxic if your cat licks your skin.
⚠ Lavender Diffusers
Very risky.
Can cause respiratory distress and toxicity through inhalation.
✔ Lavender Scented Items WITHOUT real oil (rare)
Sometimes safe, but ingredients must be verified.
Do Cats Like Lavender?
Most cats are naturally repelled by lavender.
Lavender often triggers avoidance behavior:
- Backing away
- Turning head
- Walking in the opposite direction
Cat owners sometimes use lavender oil near furniture to repel cats — which works, but is dangerous.
A small subset of cats might chew lavender out of curiosity.
These cats are at greater risk of toxicity.
Symptoms of Lavender Poisoning in Cats
If a cat ingests or inhales lavender, symptoms can appear within 30 minutes to several hours.
Digestive Symptoms
- Vomiting
- Diarrhea
- Drooling
- Loss of appetite
- Nausea
Neurological Symptoms
- Lethargy
- Weakness
- Tremors
- Unsteady walking
Respiratory Symptoms (especially from diffusers)

Can Cats Eat Lavender Leaves or Flowers?
No.
Even small amounts of the actual plant can irritate the stomach and liver.
Lavender in ANY form — fresh, dried, or cooked — is unsafe.
Are Lavender Essential Oils Safe for Cats?
Absolutely not.
Lavender essential oil is one of the most dangerous forms for cats.
Cats can be poisoned simply by:
- inhaling diffused lavender oil
- absorbing it through skin contact
- licking residue off surfaces
- touching humans who wear lavender lotions/perfumes
Lavender oil can cause:
- liver damage
- neurological symptoms
- respiratory distress
- skin burns
Never diffuse lavender oil around cats.
Are Lavender Candles Safe for Cats?
Most lavender candles contain synthetic fragrances or essential oils.
Both are unsafe.
Burning candles releases vaporized compounds that cats inhale → causing toxicity over time.
Safer alternatives: use unscented candles.
Are Lavender Plants Safe to Keep at Home?
Lavender plants should not be kept inside homes with cats.
If grown outdoors, ensure:
- Your cat cannot nibble the plant
- It is fenced or elevated
- Essential oil runoff cannot reach the cat
Outdoor lavender is still mildly dangerous but less risky than indoor exposure.
What To Do If Your Cat Eats Lavender?
1. Stay calm
Lavender poisoning can be treated if handled early.
2. Identify the form
Fresh plant? Dried? Oil? Diffuser?
3. Remove all lavender from reach
4. Check for symptoms
Monitor your cat for vomiting, drooling, weakness, tremors.
5. Contact your veterinarian immediately
Especially if:
- The cat ate the essential oil
- Symptoms are moderate or severe
- The cat is young, old, or has health issues
6. Do NOT induce vomiting unless a vet instructs you
Essential oils can cause aspiration if vomiting occurs incorrectly.
7. Bring packaging or samples to the vet
Helps with diagnosis.
