Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Drooling, vomiting, diarrhea, and potential skin irritation upon contact.
Escalation note
Symptoms are generally mild but can cause significant gastrointestinal distress. Please contact your veterinarian if your cat has ingested any part of the plant.
First aid at home
Remove any remaining plant material from the mouth and offer water or a small bland meal to dilute the oils orally. If oils touched the skin or coat, bathe with mild liquid dish detergent. Do not induce vomiting and do not give activated charcoal — both can worsen essential-oil exposure.
What to watch for
Vomiting and diarrhea are the most common signs. Look for lethargy, a depressed mood, drooling, and loss of appetite. With heavier exposure, watch for skin redness or photosensitivity (irritation worse on sun-exposed skin like the belly or ear tips) — uncommon but a citrus-specific clue.
Time window
Signs typically appear within 6 to 8 hours of ingesting essential-oil-containing material. Mild plant-ingestion cases generally resolve in 24 to 48 hours with supportive care.
When to call the vet
Call your vet, or ASPCA Poison Control at (888) 426-4435, if vomiting or diarrhea continues past a few hours, your cat is unusually lethargic or won't eat, or you see any skin redness. Concentrated citrus essential-oil exposure (oils, diffusers, peel concentrates) warrants an immediate call — cats handle these much worse than the fruit itself.
What this means for your cat
Cats are unusually sensitive to citrus oils — they lack key liver enzymes that other species use to break the oils down — so even a small nibble of leaf, peel, or unripe fruit can cause real GI upset. The plant is toxic but not usually life-threatening; a leaf or two reads as 'sick stomach,' not emergency.
