Cat Throwing Up Undigested Food. As a result, your cat might be throwing up food that’s undigested, as well as blood or vile. The examples of the gastrointestinal issues a cat may have are irritable bowel syndrome, intestinal parasites (tapeworm or roundworm), intestinal blockages due to hairballs or swallowed foreign objects, or even.

In some cases, cats suffering from this syndrome will only vomit gastric juice. The food that she vomits will appear somewhat digested and it will be accompanied by a yellow fluid, known as bile. Having your cat throw up undigested food is not normal in cats, and it may indicate a more serious health problem in your feline companion.
