Cat Vomit Appearance

Clear cat vomit is as clear as the name suggests, it may come out as a clear liquid or as a white foam. You do not expect to see any solid food particle in this type of vomit.

The clear liquids always come from the cat’s digestive tract, which in many cases are stomach juices. Some of the common reasons why a cat would emit the foam or clear liquid include:


The presence of hairballs in the cat is an indication that the cat wants to get the hairball out of the stomach. Before the hairball comes out, a gastric liquid will precede its removal.

The best way to avoid this from occurring in the future is to groom your cat by removing excess fur as you increase its fiber intake. If the problem persists with no hairball coming out, kindly visit the nearest veterinary clinic.


When a cat foams through its mouth due to the following reasons:

  • Eating too quickly or too much, to resolve this, introduce the cat to a slow feeder that will keep him from eating too fast and try and space his meals to avoid giving so much at once.
  • Change of diet can also lead to an upset. Introduce gradual changes when adding or removing something to the cat’s diet
  • When the cat is hungry, too much acid in the stomach may rise and come through the mouth. Lack of food in the stomach irritates because of the excess acid and thus causing vomiting
  • Gastroenteritis and irritable bowel syndrome are some of the severe stomach conditions that may also produce white foamy liquid.
    Your veterinarian may offer the best prescriptions to cure these two stomach-related illnesses. There are specific diets that the vet can suggest to manage the effects gastroenteritis and irritable bowel syndrome.
  • Nauseas or loss of appetite due to cancer, diabetes, and kidney diseases can also force the cat to vomit foam or clear liquid.

  1. Hi there! I have a precious 3 month old kitten, and as of yesterday Feb 25, until today he’s hardly eating. He ate more yesterday. He’s sleeping alot, not playful anymore, he drinks but not his usual amount. He even looks sad. He vomited clear liquid twice , but I also noted green vomit yesterday. All of these activities occured after he spent sometime playing outside of the house with his mother. I already lost his sister today whom was in a worst condition than him. But unfortunately the vet wasn’t open due to it being a national holiday in my country. What is your advice? Thank you!

  2. I bathed my cat with dawn dish soap yesterday and had to scrub around her mouth for acne. ..soap got into her mouth…not sure how much she swallowed. She has been throwing up this foam which I thought it was soap. She has been throwing it up. Should it have stopped by now? It’s been 12 hours since her shower

  3. It makes sense to talk to a specialist if you really want to learn what the issue with your cat is because they have the proper training. My brother just adopted a cat that is having some health issues and is throwing up. I’ll try to share your article with him so that he can find a vet nearby that can help.
