Weight Loss

At one point or another, animals may experience weight loss for various reasons. However, weight loss substantial enough to cause a dramatic change in appearance could indicate a tumour. Depending on where the tumour is located, the intestine becomes dysfunctional or blocked and causes weight loss. The cat becomes uninterested in food. It is important to recognise this symptom as a major telling sign of feline stomach cancer.


Lethargy is a common symptom of feline stomach cancer. If your cat is usually playful but suddenly lacks energy and playfulness, or begins sleeping more than normal, you should consult your veterinarian.

Inability To Heal

If your cat has sores that are unable to heal, seek the opinion of a qualified veterinary professional as this is a sign of feline stomach cancer.

Problems With Bodily Functions

Feline stomach cancer directly affects the gastric system of the body. Therefore, bloody vomit and stools and digestive problems are the most common stomach cancer symptoms. Also, difficulty breathing is common among feline stomach cancer patients. If you note any bloody stools and vomit, or problems with digestion, contact a veterinary professional.
