Safety status
What this means for your cat
Cats: eucalyptus is meaningfully more dangerous to cats than to most other pets. Cats lack a key liver enzyme used to clear essential-oil compounds, so eucalyptol can build up rapidly — leaf-nibbling is usually mild, but exposure to diffused or topical eucalyptus oil can become severe quickly.
What to watch for
ASPCA lists salivation, vomiting, diarrhoea, and depression. Pet Poison Helpline adds drooling, lethargy, anorexia, and respiratory, dermal, and mucous-membrane irritation. With concentrated oil, watch for tremors, seizures, or signs of kidney injury (decreased urination, refusal to drink).
Time window
Pet Poison Helpline notes that signs from essential-oil exposure typically develop within 6–8 hours.
When to call the vet
Call your vet or Pet Poison Helpline (855-764-7661) at the first sign of drooling or vomiting after eucalyptus contact, or immediately if your cat licked, walked through, or was exposed to a diffuser/topical containing eucalyptus oil.
First aid at home
If eucalyptus oil is on the skin or fur, Pet Poison Helpline says to wash it off quickly using liquid dishwashing detergent. Do NOT induce vomiting and do NOT give activated charcoal at home — both can worsen the cat's condition. Bring the product packaging with you to the clinic.
