Many cat owners may think that it is ok if the cat throws around vomit regularly. But a piece of wise advice will be to have it checked with the vet if the vomiting episodes are often and recurrent. This might be a clear indication of stomach issues, and if in particular white foam, the problem could be even more severe.

Vomiting: An indication of gastro issues  

One of the multiple reasons underlying   cause of cats throwing up white foam and not eating is the disordered digestive system. While making a diagnosis of gastro issue, it is also essential to check the frequency of vomiting. That is, if it is periodic or happening recurrently. Also, vomiting episodes could be of two kinds: acute and chronic.

Here, an acute episode of vomiting would refer to a short time or sporadic duration of vomiting. One suffering with this kind vomits multiple times over a quick spread of time. On the contrary, chronic vomiting hints at churning out the gastric content over a long spread of time.

Observing Behavior 

While considering either type of vomiting, it is also essential to check for accompanying symptoms. Plus, it needs to be put into the current situation or context of the cat’s profile.

  • For instance, one should see if the cat vomits after certain activities, let’s say consuming food or while playing around.
  • One needs to observe a cat when it is fed with food or milk. See if it throws over the smell of food or after taking it down in the stomach.
  • Most of the time, the cat cannot keep the food down, and every time it is fed, it will throw it out.
  • And while the cat keeps vomiting, the next thing will be to observe the foam-like appearance and if it contains yellowish bile.
  • The color and consistency of the vomit are other things to be taken into account. This will help in drawing the correct diagnosis.
  • One might see some added content inherent to the vomit. One such thing is blood, and the other might be green slimy mucous.

One common gastro disease seen with a cat is known as feline panleukopenia. The underlying cause is a virus that makes its way into the cat’s body, causing the bloody outflow of feces and vomit.

Causes of vomiting other than gastro

More accurately referred to as either acute or chronic, require its own kind of treatment. However, it can occur in the company of any other medical condition like gastro, liver issues, or diabetes.

Most of the animals can regurgitate them and put out the mass, while in cats, it stays and causes gastro irritation.   This might also, at times, lead to obstruction, i.e., called intussusception. This precisely means the entry of something within a part of the intestine, particularly within the fluid. In this case, the situation is grave most of the time and may require surgical intervention.
