Do you have to seal the windowsill balcony if you have a cat?

It's not that you have to, but you have to make sure that you have space so that the cat can't get out. For example, close doors and windows when you're away, something like that.

As long as you can watch, it's not impossible to leave the window open while you're there. Also, if you don't want the cat to go where and where to go, for example: go out, go to the table, go to bed.

Then never let it on, don't let it out. In this way, it forms a habit, and it is naturally very timid and unfamiliar to do these things.

Also, if you are on the first floor or in a bungalow with a free-range cat or dog. Then you must make sure that the cats and dogs can go out and come back. Most domestic cats and dogs run away and get lost.

In fact, when they came back, the doors and windows were closed, and they couldn't get in, so they left on their own. Because it has food, drink and shelter in your place, as long as it can come back, its first choice must be to come back, and only when it can't come back for the first time will it leave.

Of course, if you don't succeed in coming back the first time, it will be difficult to come back in the future.
