What's going on when a kitten throws up yellow fluid?

There could be several reasons for a kitten to throw up yellow fluid. First, consider gastroenteritis. When a kitten has gastroenteritis, they may also vomit yellow fluid. In this case, it's best to go to the hospital for inspection. Secondly, consider foreign objects in the stomach, including hairballs. Foreign objects in the stomach can cause vomiting and even yellow fluid in the kitten, and in this case, the kitten usually shows a decrease in appetite. Lastly, it could be a viral infection, which can also cause vomiting in kittens.

1. Acute gastroenteritis can be caused by sudden changes in weather or other irritating factors. It commonly manifests as vomiting, and the yellow fluid may be a mixture of gastric juice and yellow-green bile. Apart from these stress-induced causes, if a kitten accidentally eats spoiled cat food or other foods, it can lead to gastrointestinal infection and inflammation. Parasitic infections can also cause gastroenteritis. In these cases, it's essential to go to the hospital for a systematic examination, accurate diagnosis, and targeted treatment.

2. Kittens are playful and curious at this age, and they easily swallow small foreign objects. These objects can cause food to be unable to pass through the digestive tract smoothly. In this case, surgery may be necessary. Hairballs inside the body can also cause kittens to vomit yellow fluid. Regularly administering hairball remedies can help promote the elimination of hairballs.

3. Virus infection. Immunocompromised kittens are most susceptible to viral infections. Unvaccinated kittens should have a vomiting episode immediately tested for a virus. If a viral infection is confirmed, timely treatment and observation are necessary. The earlier the infection is detected, the higher the chances of recovery.
