Verified against ASPCA/provenance audit 2026-05-06 on May 6, 2026.
Signs to watch for
Vomiting, diarrhea, lethargy, and potential photosensitivity.
Escalation note
Ingestion of plant parts or essential oils can cause gastrointestinal upset and skin irritation. Please contact your veterinarian if your cat has ingested any part of this plant.
What to watch for
Most common: vomiting, diarrhea, and depression (the cat goes quiet, hides, stops grooming). Drooling and pawing at the mouth from oral irritation are also typical. With heavier exposure or essential-oil contact on skin, watch for tremors, weakness, and — on lightly haired areas like the ears, nose, and belly — photosensitivity reactions (redness, dermatitis) after sunlight exposure.
Time window
GI signs typically begin within 2–6 hours of ingestion. Photosensitivity reactions, when they occur, develop over the next 1–3 days with sun exposure. ASPCA does not publish a recovery window; uncomplicated cases generally improve within 24–48 hours with supportive care, but exact timing is not well documented.
When to call the vet
Call your vet or ASPCA Animal Poison Control (888-426-4435) right away if your cat has chewed the peel or leaves and is vomiting repeatedly, very lethargic, drooling, or unsteady on its feet. Topical exposure to bitter-orange essential oil is its own emergency — call before bathing, as the wrong solvent can drive the oil deeper.
What this means for your cat
Cats — toxic. ASPCA classifies bitter orange as toxic to cats; the toxic principles are essential oils (limonene, linalool) and psoralens concentrated in the peel and leaves. Cats are notably more sensitive to citrus oils than dogs because they metabolize these compounds slowly, so even small amounts of chewed peel or oil residue on fur can cause real signs.
