Vomiting in cats can be alarming for any pet parent. While the occasional hairball may not be a cause for concern, frequent or severe vomiting could be a sign of an underlying health issue. Understanding the possible reasons behind your cat’s vomiting can help you take the proper steps to keep them healthy.
In this blog, we’ll cover the common causes of cat vomiting, when it becomes a concern, how to prevent it, and when to call the vet.
Common Reasons Cats Vomit
There are many reasons why cats vomit. Some are relatively harmless, while others require veterinary attention.
1. Hairballs
Cats spend a lot of time grooming, which causes them to ingest loose fur. While most of this fur travels safely through their digestive system, some of it can accumulate and be vomited out as a hairball. This is generally normal, particularly for long-haired breeds such as Maine Coons and Persians.
2. Eating Too Quickly
Some cats eat too fast and vomit undigested food shortly afterward. This usually happens if they feel overly hungry or compete with other pets for food.
3. Dietary Indiscretion
Cats are curious creatures. If they eat spoiled food, non-food items (like string or rubber bands), or toxic plants, they may vomit in response.
4. Food Intolerance or Allergy
Some cats may develop an intolerance or allergy to ingredients in their food, such as grains, dairy, or specific proteins. This can lead to chronic vomiting, diarrhea, or skin issues.
5. Sudden Food Changes
Switching your cat’s food too quickly can upset their stomach. Always introduce new food gradually over 7–10 days.
6. Parasites
Intestinal worms or other parasites can irritate the stomach lining and cause vomiting, especially in kittens or outdoor cats.
7. Infections and Illnesses
Viral or bacterial infections, liver or kidney disease, pancreatitis, and hyperthyroidism are some medical conditions that can cause vomiting. These often accompany other symptoms like lethargy, weight loss, or diarrhea.
8. Foreign Objects
If your cat swallows a non-digestible object like a hair tie or a small toy, it could block the intestines and cause vomiting. This is a medical emergency.
When Is Cat Vomiting a Concern?
While an occasional episode of vomiting (especially with hairballs) is typical, you should monitor the frequency and symptoms. Seek veterinary help if:
- Vomiting occurs more than once a week
- Your cat vomits multiple times a day
- There is blood in the vomit
- Vomit looks like coffee grounds (possible sign of internal bleeding)
- Your cat seems lethargic, refuses to eat, or is losing weight
- There’s accompanying diarrhea or dehydration
- Your cat is a kitten or senior—both are more vulnerable to illness
How to Prevent Vomiting in Cats
While not all cases are preventable, some habits can reduce the chances of vomiting:
1. Brush Your Cat Regularly
Regular brushing removes loose fur and reduces hairball formation. Long-haired breeds may need daily grooming.
2. Use a Slow Feeder Bowl
If your cat gulps down food, use a slow feeder or puzzle feeder to help them eat more slowly and avoid regurgitation.
3. Stick to a Consistent Diet
Avoid abruptly changing your cat’s food. If a change is necessary, mix the new food with the old in increasing amounts over a week.
4. Provide Clean Water and a Healthy Diet
Ensure fresh water is always available, and if necessary, feed your cat high-quality, easily digestible food with limited ingredients.
5. Keep Toxic Items Out of Reach
Remove access to houseplants (like lilies), rubber bands, thread, and other objects your cat may try to chew or swallow.
6. Regular Deworming and Vet Visits
Routine deworming and annual checkups can catch and treat issues before they become serious.
Treatment Options
Treatment depends on the cause. Mild vomiting may not need medication, but chronic or severe cases require veterinary diagnosis. Your vet may recommend:
- Blood tests or X-rays
- Anti-nausea medication
- Fluids to prevent dehydration
- Prescription diets
- Surgery (in case of intestinal blockage)
Never give your cat over-the-counter medications meant for humans.
Final Thoughts
Vomiting in cats is common, but that doesn’t mean it should be ignored. Always watch for patterns or changes in your cat’s behavior, and don’t hesitate to consult your vet if you’re concerned.
With proper care, a balanced diet, and attention to their habits, you can help your feline friend stay healthy and happy.
