My cat ate Eucalyptus - what should I do?

Eucalyptus species

Potentially toxic

Contact your veterinarian or an animal poison-control resource now, especially if any amount was chewed or swallowed.

Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.

Safety verdict

Consulted references classify the plant as toxic or irritating for that pet type.

Signs to watch for

Salivation, vomiting, diarrhea, and depression.

Escalation note

Ingestion can lead to gastrointestinal distress. Please contact your veterinarian or an animal poison control center if you suspect your cat has ingested any part of this plant.

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.

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.

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.
