Question: what does it mean when a cat throws up mucus?
Answer: Bring a sample of the vomit to the veterinarian. ... If the vomit contains excessive amounts of mucus, an inflamed intestine may be the cause. Undigested food in the vomit can be due to food poisoning, anxiety, or simply overeating. Bile, on the other hand, indicates an inflammatory bowel disease or pancreatitis.
