Is Lavender Oil Safe for Cats?
Why it’s a problem
The same linalool that makes lavender smell nice is a terpene, and cats metabolize terpenes very poorly. Ingested or well-absorbed, it causes stomach and nervous system signs; cats are also more sensitive to inhaled oils because they cannot process what they groom off their own fur.
How to keep your pet safe
Diffuse only briefly in a large room the cat can leave, or not at all. Never apply to the cat or to surfaces the cat grooms. Wipe up any spill immediately.
Warning signs to watch for
Drooling, vomiting, lethargy, wobbliness, tremors in larger exposures; drooling alone often appears right after a spill is licked.
When to call the vet
Call your vet if oil was licked off fur or skin, or if any symptoms appear. Fresh air and a call are enough for brief sniff-only exposure.
Common questions
Are lavender plants also dangerous?
The live plant is mildly toxic (stomach upset) but far less concentrated than the oil. Cats rarely eat enough plant to be seriously harmed — the oil is the real hazard.
Is a lavender-scented litter or cleaner safe?
Lightly scented finished products are usually tolerated, but strong fragrance near the litter box can make cats avoid it. Watch for drooling or avoidance and switch if seen.
