Question from Arlene:

My Himmy, Misha is almost 18 (12/21). He is healthy, his coat is shiny and thick, and his appetite is strong. At his age, he is not too active, but sometimes he still wants to play for a little while. The only problem I have is that almost every day he vomits. Not food or hairballs, but a loose, watery stuff. Nothing solid at all. I hesitate taking him to the vet, because whenever I do, he comes home sicker. He is very high strung. I hope you can help me. Thank you.

Answer from Amy:

Hi Arlene,

Your cat is probably vomiting bile on an empty stomach.

There are many reasons that cause a cat to vomit. Cats seem to have a more sensitive digestive tract than most other species. Some cats retch frequently, but do not show signs of illness such as weight loss, dehydration, diarrhea, and loss of appetite. It is difficult to determine the culprit of vomiting in these cats.

Most of cats’ vomiting problems are caused by consuming things they cannot digest. However, other common causes are inflammatory bowel disease, kidney disease, hyperthyroidism, heartworms, cholangiohepatitis, pancreatitis and cancer according to Dr. Mike Richards. Also, Infectious diseases or parasites can induce vomiting. Physical obstructions in the digestive tract can also upset a cat’s stomach, but sometimes it is accompanied by foul odor from the rear and loss of appetite.


First of all, you can try to figure out the severity of your cat’s vomiting. If he is retching frequently and losing more water than he could replenish, it is important to have him seen by a vet ASAP. Severe vomiting can indicate an obstruction in the digestive system. Physical obstructions are usually treated with IV fluids, but sometimes they can only be removed surgically. However, if the vomiting is intermittent and your cat is able to retain water, you can try the following home remedies recommended by Nelson Animal Hospital.

Cats have a sensitive stomach. If food cannot be digested, it is very possible that it will end up being ejected through the mouth. Cat vomiting is not surprising to cat owners. However, if vomiting persists and the cat is showing abnormal signs of behavior, it is critical to have the cat seen by a veterinarian right away.

What are the causes of vomiting in cats?

The causes are various. They range from food or diet to diseases or even infections.


  1. Eating too rapidly which impedes food digestion
  2. Switching to a new diet too quickly. When a new brand of food is introduced, cat owners should take a few days to gradually transit to the new diet for their cat in order to prevent vomiting
  3. Expired food, stale food, inappropriate food for cats, etc
  4. Food allergies
  5. Food intolerance such as food that contains lactose or human food
  6. Foreign object that is not supposed to be ingested by a cat
  7. Toxic plants – many plants are toxic to cats. Click here to see a list of plants that are poisonous to cats
