TL;DR: Laundry detergent ingestion in cats can cause severe chemical burns and life-threatening aspiration pneumonia. If your cat licks detergent, contact a veterinarian immediately and do not induce vomiting at home.
What happens if my cat licks or eats laundry detergent?
Laundry detergents, especially concentrated liquid versions and pods, contain powerful surfactants and chemicals designed to break down stains. When a cat licks these substances, the chemicals can cause corrosive injuries or chemical burns to the sensitive tissues of the mouth, esophagus, and stomach. Additionally, if the detergent foams, there is a high risk of the cat inhaling the suds, which can lead to life-threatening aspiration pneumonia.
Is it a medical emergency if my cat licks liquid laundry detergent?
- Urgency Level: The risk is considered Medium, though concentrated formulas are significantly more dangerous than diluted versions.
- Symptoms: Monitor your pet closely for signs of excessive drooling, coughing, or vomiting.
- Critical Warning: Do not induce vomiting at home, as the foam can be inhaled into the lungs, leading to pneumonia.
- Next Steps: Contact your veterinarian or a pet poison control center immediately for guidance based on the specific amount and type of detergent ingested.
Why should I take a photo of the detergent label for the veterinarian?
If you are calling a vet or a triage service, taking a photo of the detergent's ingredient list and the brand name is incredibly helpful. Different brands use various concentrations of surfactants and ionic/non-ionic chemicals. Providing a clear image of the packaging allows the veterinary professional to quickly identify the specific toxins involved and determine the exact level of risk and the necessary treatment plan.
Clinical Context (Merck Veterinary Manual)
Following ingestion of liquid laundry detergent, cats may exhibit nausea, vomiting, and diarrhea. Mild ocular irritation with lacrimation and blepharospasm is possible. Exposure to detergents containing sodium lauryl sulfate may lead to moist respiratory sounds, cyanosis, and dyspnea within 1-3 hours. Cationic detergents, present in some formulations, can cause oral ulceration, stomatitis, pharyngitis, hypersalivation, swollen tongue, depression, vomiting, abdominal discomfort, and increased upper respiratory noises within 6-12 hours of ingestion. Systemic effects of cationic detergent exposure can include metabolic acidosis, CNS depression, hypotension, coma, seizures, muscular weakness and fasciculation, collapse, and pulmonary edema. Treatment involves dilution with milk or water to reduce the risk of spontaneous vomiting. Antiemetics, such as metoclopramide (0.2-0.4 mg/kg, PO, SC, or IM, qid), may be required in severe cases. Parenteral fluid therapy may be necessary in rare instances.
