You should pay attention to the cat's mood when you first bring it home to avoid the cat's stress reaction. It is best to let the cat adapt to the new environment first, deworm the cat after a week, and then take the cat for vaccination after a week of deworming. Do not bathe the cat during this period. Moreover, it is best not to change the food of a cat that has just been brought home, and do not move it randomly after preparing the food, water, bowl and litter box for the cat.
