Cats must be in good health before being vaccinated. If they have a fever, cold, etc., do not vaccinate the cat casually. It is best to consult a professional pet physician. It is recommended to place a small book at home to record the vaccine time so that the doctor can determine the cat's immunity time. Half an hour after the vaccination, the owner should pay close attention to the cat's condition, because a very small number of cats will have certain allergic reactions and should immediately ask a doctor for desensitization treatment. After vaccination, the cat's immunity will be reduced, so it is recommended not to take a bath for about a week, as it is easy to catch a cold. You can clean parts of the cat, such as legs and buttocks.
