Why Ammonia Cleaners Are a Household Hazard
Ammonia is a strong alkaline corrosive found in many window, floor, and bathroom cleaners across the US and UK.
Ingestion causes immediate burning of the mouth, esophagus, and stomach lining, and inhalation of fumes can damage the respiratory tract.
Cats are especially at risk because they may walk on freshly mopped floors and then groom themselves, transferring the chemical to their mouths.
Never mix ammonia-containing products with bleach, as this releases toxic chlorine gas that is fatal to pets.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Signs to watch for
- Excessive drooling and pawing at the mouth
- Vomiting, sometimes with blood
- Difficulty breathing or wheezing
- Red, irritated, or burned-looking oral tissues
- Coughing and nasal discharge
- Weakness and collapse in severe cases
What to do right now
- Call your veterinarian or a pet poison helpline right away for guidance.
- Do not induce vomiting, as this re-exposes the esophagus to the corrosive chemical.
- Rinse the pet mouth gently with cool water if they are conscious and able to tolerate it.
- Wipe any residue from the fur with a damp cloth to prevent further licking.
- Keep the pet calm and transport to a veterinary clinic if breathing difficulties develop.
