Falls From Height: The First Rule of Keeping a Cat in Hong Kong

Homes in Hong Kong are mostly high up, which makes windows and balconies somewhere a cat goes in the course of an ordinary day. That is very different from places built around houses and low-rise flats. Veterinary organisations describe cats falling from height as “not uncommon” in urban emergency rooms — that is the standard phrasing in the field, not a rate. We searched the official sources (the Fire Services Department, the SPCA annual reports, the veterinary association) for a figure we could cite — how many cases a year — and there is not one. We would rather say that plainly than pad the page with a number circulating online that we cannot trace to a source.

Why cats go off buildings has little to do with carelessness and a lot to do with instinct. A cat judges height against the distances it deals with every day, and an unfamiliar drop is not something it reads accurately. When there are birds, insects or movement in the flat opposite, the cat’s attention is entirely on the prey; what floor it is standing on does not enter into it. An open window reads to us as an opening. To a cat it is not automatically a boundary — once it is open, it has stopped being an obstacle.

Insect screens get mistaken for something that will stop a cat. They were designed to keep mosquitoes out, not to take the weight and momentum of an animal. A cat that launches at one can easily pop it out of the frame, which also teaches her that this is a place that opens. Window netting is a different product: the load rating and the way it fixes to the frame exist specifically to hold a cat.

That is why several animal welfare organisations here, Hong Kong Cat Society and Paws United Charity among them, make installing window netting a condition of adopting a cat — and specify the mesh must be narrower than the cat’s head, generally within about 1.5 inches, so she cannot push her head through and get stuck or fall. This is not the groups piling on requirements to frighten people. It reflects a settled view in the field: netting is not a bonus, it is one of the thresholds of keeping a cat.

“What I am really afraid of is her going over the edge” — that is the plain worry for owners living high up, and it is why the netting requirement exists. In February 2026 there was a real case in Kowloon City: a 63-year-old man saw his cat fall from the balcony, reached out to try to catch her, lost his footing and fell to his death. The cat was later rescued by the Fire Services Department and the SPCA. One case carries no statistical weight. But it shows something clearly — what the netting guards against is not only the loss of the cat. Once it happens, a person can be pulled into the emergency too. That lands harder than any abstract number.

On the practical checks: netting is not simply a matter of having some. Air-conditioner casings, window boxes and balcony awnings are all stepping stones from a cat’s point of view, and if the netting does not cover them you have left a back door open. After installation, check periodically for anything working loose or pulled at where the net meets the frame, especially on whichever side she likes to launch at.

Framed correctly, this is not a question of whether you can be bothered. If you live high up and there is a window or balcony she can reach, netting is one of the preconditions of keeping a cat — on a level with buying food and a litter box, not an accessory you get around to later.
