As cat parents, it’s common to find your feline friend throwing up from time to time. While occasional vomiting is usually harmless, frequent or unusual episodes can be a sign that something more serious is going on. Let’s dive into the common reasons cats throw up, what they might expel, and when it’s time to visit the vet.
Common Reasons Cats Throw Up
1. Hairballs
Cats are fastidious groomers, which means they end up swallowing a lot of fur. This fur sometimes clumps together in their stomach, forming hairballs.
When It’s Normal: Occasional hairball vomiting is normal, especially in long-haired breeds.
When to Worry: If your cat frequently throws up hairballs or seems to have difficulty passing them, it may indicate excessive grooming or digestive issues.
Tip: Regular brushing and specialised diets for hairball control can help reduce the frequency.
2. Eating Too Quickly
Some cats scoff down their food too quickly, leading to regurgitation of undigested food shortly after eating.
Tip: Try using a slow-feeder bowl or feeding smaller, more frequent meals.
3. Dietary Issues
Changes in diet, food intolerance, or spoiled food can upset your cat’s stomach.
Tip: If you’ve recently switched your cat’s food and noticed vomiting, try transitioning more slowly or consult your vet about alternative options.
4. Grass or Plants
Many cats munch on grass or indoor plants, which can cause them to vomit.
When It’s Normal: Occasional vomiting after eating grass is typically harmless and may help with digestion.
When to Worry: Make sure your cat isn’t chewing on toxic plants, which can cause severe health issues.

5. Bile (Yellow or Green Liquid)
Vomiting bile usually happens when a cat’s stomach is empty for too long or there is gastrointestinal irritation.
Tip: Feeding smaller, more frequent meals can help prevent bile vomiting.
6. Foreign Objects
Cats are curious creatures and sometimes ingest non-food items like string, small toys, or pieces of plastic.
Warning: This is a serious issue that can cause intestinal blockages. If your cat vomits foreign objects or shows signs of distress (e.g., lethargy, lack of appetite), seek immediate veterinary care.
7. Parasites
Vomiting can sometimes be caused by intestinal parasites, such as roundworms or tapeworms.
Tip: Regular deworming, as recommended by your vet, can help prevent this.
8. Foam or Clear Liquid
This type of vomiting may indicate acid buildup or an empty stomach.
Tip: Feeding your cat more frequently can help reduce this type of vomiting.
9. Blood (Bright Red or Coffee-Ground Appearance)
Vomiting blood is a serious sign and may indicate gastrointestinal injury, ulcers, or other critical issues.
Action: Seek immediate veterinary attention if your cat vomits blood.
10. Food with Mucus
Mucus in vomit can be a sign of gastrointestinal inflammation.
Action: If this occurs frequently, consult your vet to check for underlying digestive issues.
When to See the Vet
While occasional vomiting may not be a cause for concern, frequent or severe episodes warrant a trip to the vet. Here are some signs that it’s time to seek professional help:
Vomiting more than once or twice a day
Lethargy or unusual behaviour
Loss of appetite
Weight loss
Diarrhoea
Vomiting blood or foreign objects
Your vet may recommend diagnostic tests such as bloodwork, X-rays, or ultrasounds to determine the cause of persistent vomiting.
How to Prevent Vomiting in Cats
Here are some proactive steps to reduce your cat’s chances of throwing up:
Regular Grooming: Brush your cat regularly to minimise the amount of fur they ingest, especially if they have long hair.
Slow Feeding: Use slow-feeder bowls or puzzle feeders to prevent your cat from eating too quickly.
Choose High-Quality Food: Ensure your cat’s diet is balanced and free from ingredients that may upset their stomach.
Avoid Toxic Plants: Keep harmful plants out of your home and offer safe alternatives like cat grass.
Regular Vet Check-Ups: Routine veterinary visits help catch potential health issues early.
Vomiting in cats can range from normal behaviour to a sign of a serious health issue.
