White Foam: Harmless or a Cause for Concern?

Does your cat vomit white or yellow foam and not eat? It doesn’t always have to mean something bad. The body uses vomiting as a protective mechanism to get rid of things that it doesn’t think belong in the stomach. Read here what exactly can be behind white foam in cats.

Cat Vomits Foam

  • Cats excrete a lot of fluids when they vomit;
  • This can be life-threatening for older cats and young animals;
  • Depending on the general condition of the cat, it should be seen by the vet.

If the cat vomits white foam or watery sputum, most of the time food is broken out with it. The color of the gagged contents of the stomach can be pink if there is slight bleeding in the hair or capillary vessels of the gastric mucosa.

If the vomiting lasts longer than 24 hours and the vomit smells bad, you should urgently consult a veterinarian.

Cat Vomits White Foam – Why?

There are several reasons cats vomit foam. It can be a harmless upset stomach, but it can also be a serious illness:

  • Gastrointestinal diseases
  • Food intolerance
  • Diabetes
  • Kidney disease
  • Thyroid disease
  • Poisoning (poisonous plants, foods, or other triggers)
  • Stress

When Does the Cat Have to Go to the Vet if the Phlegm is Light?

If the cat has been vomiting for more than 24 hours or if other symptoms occur, you should see a veterinarian. Such side effects can be:

  • Fever
  • Apathy
  • Unwillingness to eat
  • Bad breath
  • No need to urinate
  • Strong thirst
  • Diarrhea
  • Bad general condition

Light Slime: How is the Diagnosis Successful?

For the diagnosis, cat owners should look closely and observe the behavior of their velvet paws. Describe to the vet when the cat is vomiting and at what intervals. You should also state what the cat is eating and whether there are sick animals in the area that the cat could have been infected by.

The vet will come to a diagnosis with various examinations. He may need to do an ultrasound or an X-ray. A blood test may also be needed.

Cat Vomits Phlegm: What to Do as an Owner

If the cat vomits and spits white foam, it should not be able to eat for four hours. Likewise, she shouldn’t drink during that time. You can then give her water or an electrolyte solution from the pharmacy. However, not all velvet paws are fans of such electrolyte solutions.

The dose should be repeated every two to four hours. If the cat has to vomit the fluid again, she should see a vet. If she keeps the liquid, do not give her anything to eat for 24 hours.

Light food and just no dry food

After that time, she gets light food that irritates the stomach as little as possible. Lean poultry like chicken or turkey is good for this. The meat can be fried (in a little vegetable oil) or boiled, but without spices. You should remove bones, skin, and fat beforehand and then feed the tender meat in small pieces.

Dry food is completely unsuitable if the cat vomits foam. Since this food has only seven percent moisture, it irritates the stomach lining and deprives it of fluids. In the event of vomiting, this would be counterproductive.
