🔴 HIGH — Dangerous
Why is it risky?
Cats are exceptionally sensitive to acetaminophen because they lack the liver enzyme needed to safely process it. It damages red blood cells and causes severe liver toxicity, and is one of the most common fatal human-medication poisonings in cats.
Affected Systems
Liver · Cardiovascular · Respiratory
Symptoms
Swelling of the face/paws, brown or blue-tinged gums (methemoglobinemia), difficulty breathing, vomiting, lethargy, jaundice. Onset within 1–4 hours.
What To Do
Veterinary emergency, go immediately, do not wait for symptoms to appear.
Notes
Extremely time-critical; survival depends heavily on how fast treatment starts.
