TL;DR: Alcohol poisoning in cats is a life-threatening emergency that causes central nervous system and respiratory failure. If your cat ingests any amount of alcohol, contact an emergency veterinarian immediately for life-saving treatment.
What is alcohol poisoning in cats and why is it dangerous?
Alcohol, specifically ethanol, is a potent toxin for cats. Because of their small body mass and the way their liver processes chemicals, even a tiny amount of beer, wine, or liquor can cause severe metabolic disturbances. Alcohol poisoning affects the central nervous system, respiratory system, and blood chemistry, leading to potentially fatal complications.
Is alcohol poisoning in cats an emergency and what are the symptoms?
- Alcohol ingestion is a critical medical emergency as there is no safe amount for a cat to consume.
- Symptoms typically appear within 30 to 60 minutes and include staggering, vomiting, lethargy, or slowed breathing.
- If left untreated, ingestion can lead to seizures, respiratory failure, and cardiac arrest.
- Contact an emergency veterinarian or a pet poison control center immediately.
How does a photo of the alcohol label help my veterinarian with triage?
- If possible, take a photo of the drink's label or the spill to help identify the alcohol percentage.
- Photos help the veterinary team check for additional toxins like xylitol, grapes, or caffeine.
- Providing a photo allows the clinic to calculate toxicity levels and prepare life-saving treatments before you arrive.
Clinical Context (Merck Veterinary Manual)
Alcohol intoxication in cats can occur from ingestion of alcoholic beverages, rubbing alcohols, drug elixirs, or fermenting bread dough. All alcohols are rapidly absorbed via the GI tract, and most are well absorbed dermally, reaching peak plasma levels within 1.5-2 hours. Clinical signs include depression, tremors, and dyspnea, and severe cases may progress to coma, hypothermia, seizures, bradycardia, and respiratory depression. Death is generally due to respiratory failure, hypothermia, hypoglycemia, and/or metabolic acidosis. Pneumonia secondary to aspiration of vomitus is possible. Stabilization of severely symptomatic animals is a priority, with adequate ventilation maintained, and cardiovascular and acid-base abnormalities corrected. Seizures can be controlled with diazepam (0.5-2 mg/kg, IV) as needed. For asymptomatic animals, induction of emesis may be of benefit in the first 20-40 minutes after ingestion. Activated charcoal is not thought to appreciably bind small-chain alcohols and is not often recommended. Bathing with mild shampoo is recommended for significant dermal exposures.
