Question: what does it mean when a cat throws up undigested food?
Answer: Regurgitation is when cats throw up undigested food, often with little or no effort. This undigested food may be covered in mucus and shaped like a tube. Regurgitation is often brought on by coughing, difficulty breathing, oesophageal problems or foreign bodies. If your cat is vomiting foam, it's likely to be bile.
