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
Ingestion of plant material or essential oils can lead to gastrointestinal upset and photosensitivity. Please contact your veterinarian if your cat has ingested any part of this plant.
What to watch for
Vomiting and diarrhea are most common, followed by depression, drooling, and loss of appetite. With skin contact (rind, peel oil), watch for redness or dermatitis that can worsen in sunlight due to psoralen-driven photosensitivity.
Time window
Symptoms generally appear within hours of exposure; ASPCA does not publish a specific recovery duration.
When to call the vet
Call your vet or ASPCA Poison Control if vomiting persists, your cat is lethargic, you notice tremors, or any reddened or irritated skin patches appear — especially after exposure to citrus essential oils.
What this means for your cat
Cats are unusually sensitive to grapefruit because they lack the liver enzymes needed to metabolize citrus essential oils efficiently. ASPCA lists grapefruit as toxic for cats, and reactions can range from drooling and vomiting to skin irritation triggered by sun exposure after rind contact.
