Let the cat stay in a corner or a dark place by itself. At this time, the owner needs to prevent strangers from approaching, reduce other people's teasing of the cat, and allow the cat to calm down and relax. You can also prepare the food that the cat usually likes to eat and put it next to it, so that the cat can eat on its own. Cats are very wary animals and will have a stress response when exposed to new environments and strangers.
