Do not allow a cat unsupervised access to an open balcony. Ordinary railings, ledges and privacy screens are not cat containment, and a startled or climbing cat can fall or escape.
Treat the whole boundary as a system
Cats Protection advises never allowing balcony access unless it is completely cat-proof. Check the floor-to-ceiling enclosure, door, joints, drainage gaps and nearby furniture. A screen is only useful when every edge remains secure.
Remove launch points
Move chairs, shelves and cat furniture away from the rail or mesh. Do not assume a high wall is unclimbable. Wind, birds and unfamiliar noise can change a calm cat’s behaviour quickly.
Supervision is still necessary
Stay present and attentive even with a purpose-built enclosure. Check it after storms, building work or cleaning. Provide shade and water, and bring the cat inside if the surface becomes hot or the cat seems unsettled.
Create an indoor alternative
A window view behind a secure closed pane and a calm retreat such as the Koda Pod can offer choice without balcony access. Never position furniture where it compromises window or door safety.
