How to Prevent a Cat from Falling Out of a Window?

The most direct way to prevent a cat from falling is to keep windows and doors closed. If you need to open them for fresh air, install a protective screen so the cat has no chance to fall. Second, check regularly that windows, doors, and screens are securely closed, because some cats are clever and very flexible and may slip through gaps.

Also, if screens or window barriers cannot be installed, consider a safety harness or collar to tether the cat in a fixed spot and prevent falling. Finally, if you notice the cat often approaching windows or balcony edges, watch its behavior and try to move it to a safe place.
