The vomiting of kittens after vaccination may be due to the following three reasons: 1. Allergy, which means vomiting occurs within ten minutes after vaccination, indicating that the kitten is allergic to this vaccine; 2. Stress reaction, the kitten is allergic to the vaccine. It is very sensitive and easy to be frightened, so it will have a stress reaction, which is normal; 3. Gastroenteritis, because the kitten is very weak just after being vaccinated, and it is easy to be infected with the virus and cause gastroenteritis.

Tips:

It is mostly normal for kittens to vomit after vaccination. The owner should ensure that the kitten is safe before taking the kitten for vaccination. It is in a healthy state, because kittens have poor immunity and are prone to problems after vaccination.
