What should the cat do when the family goes out to travel?

My cat stayed at home alone for five days.

Sometimes when you go out to travel or go to your mother-in-law's house, cats are basically alone at home. As long as enough water, cat food and cat litter are prepared, there is no problem at all. Once I went out for a week, I left my keys with my neighbor across the street and came to add cat food once every three days. The lid of my fish tank is open, and all the cats have gone to the fish tank to drink water. People in the basin don't like drinking water, but they like drinking flowing water.

Basically, when I go out for two or three days and come back, the cat is very clingy as soon as it enters the door. I meowed at you and rubbed it back and forth. It lasted for half a day, but it was basically cold after half a day. _?
