Dealing With Vomiting in Cats


Share this  

Vomiting is a symptom of many different diseases, and depending on its underlying cause, it may be a short-lived annoyance or a sign that major troubles are afoot.

"If your cat has vomited a few times but is not in any distress, you can try treating her at home."


When Should Owners Be Concerned?

If your cat has vomited just a few times but is otherwise behaving normally, you probably do not need to rush her in to see the veterinarian. Very likely your cat has just eaten something that does not agree with her or has ingested some fur and her symptoms will pass. But, if your cat's vomiting does not resolve in a day or two, or if she is very young, very old or has a health condition that could make her unable to handle even a mild bout of vomiting, call your vet immediately.

Gastrointestinal symptoms that warrant a quick trip to the veterinarian include:

  • The sudden onset of severe vomiting
  • The presence of blood in the vomit
  • Abdominal pain
  • Weakness
  • Changes in your pet's level of awareness
  • Severe diarrhea
  • The inability to drink and hold down water

The Causes of Vomiting in Cats

The list of diseases that can cause a cat to vomit is very long:

  • Intestinal parasites
  • Hairballs
  • Dietary indiscretion
  • Inflammatory bowel disease
  • Motion sickness
  • Gastrointestinal foreign bodies or other blockages
  • Viral or bacterial infections
  • Organ dysfunction (e.g., pancreatitis, kidney disease or hyperthyroidism)
  • Food allergies or intolerance
  • Some types of poisonings
  • The side-effects of treatment with certain drugs
  • Cancer

Coming to a definitive diagnosis often requires a thorough health work-up, which may involve blood work, a urinalysis, fecal examinations, x-rays, abdominal ultrasound, specialized laboratory tests, and even exploratory surgery or endoscopy with tissue biopsies.

Treatment for Vomiting

Metoclopramide Anti-Nausea Pet Medications

If your cat has vomited a few times but is not in any distress, you can try treating her at home. Take away all sources of food and water for six to eight hours. If she does not vomit during that time, give her a small amount of water or an electrolyte solution. If she can hold that down, give her a dose of hairball remedy and offer a small meal of her regular food. If after a few hours, she has not vomited you can go back to her normal feeding schedule, but do not let her eat too much at a single sitting. If at any point during this process she starts to vomit again, see your veterinarian.

Whenever possible, treatment for vomiting should be aimed at an underlying condition, but symptomatic therapy may be necessary while a cat is recovering or if a cause cannot be found or adequately resolved. In these cases, your veterinarian may prescribe a special diet and anti-nausea medications.
