Are Citrus Fruits & Oils Toxic to Cats? Limonene & Triage
Clinical Verdict: MODERATE (Fruit) TO HIGHLY TOXIC (Concentrated Oils)
Cats CANNOT eat citrus fruits or inhale citrus essential oils. Lemons, limes, oranges, and grapefruits contain psoralens and essential oils (limonene and linalool) that feline livers cannot metabolize.
Toxic Mechanism & Agent
- Toxic Agent: D-limonene, Linalool, and Phototoxic Psoralens
- Mechanism of Action: Direct mucosal irritation combined with feline hepatic inability to conjugate monoterpenes, causing severe central nervous system depression and potential hepatic failure.
Clinical Signs & Timeline
- Onset Time: Within 1 to 4 hours post ingestion or topical exposure.
- Primary Symptoms: Profuse hypersalivation, vomiting, diarrhea, tremors, ataxia, hypothermia, cutaneous dermatitis/photophobia if rubbed on skin.
Emergency Triage Protocol
URGENT VET VISIT (If Essential Oils Ingested)
If concentrated citrus essential oil was ingested or applied to the coat, bathe the cat with mild dish soap and transport to a veterinary clinic for hepatic panel screening and supportive care.
Strict Rule S1 Warning
