You will know which balcony risks are real for a cat, which ones are overstated, and the order to deal with them.

A balcony is the only outdoors many town cats ever get. It is also where an accident happens quietly, in a second, while you are busy with something else.
The rule is mechanical. If the head clears a gap, the rest follows, because a cat folds its shoulders and hips. A space that looks narrow to you is not necessarily narrow to it.
Measure instead of guessing. Run a tape between two railings, then measure the width of your cat's skull at the cheeks. If the first number beats the second, the balcony is open.
Solid railings, glass or sheet metal, settle that point and raise the next one: they cut the airflow and turn the balcony into an oven as soon as the sun hits.
The righting reflex is real and it is fast. What it does not do is cancel the impact. Broken pelvises, broken jaws and chest injuries after balcony falls have been described by veterinary emergency services for a long time.
A low floor is not a safe floor. The cat has less time to set itself, and it sometimes lands worse than from higher up.
The part to keep: a cat that falls and then runs off still needs to be seen. Internal injuries do not bleed where you can see them.
The mesh holds a cat for a fraction of a second. What holds, or lets go, is the fixing: hooks, tensioners, anchor points in a wall that is not always solid concrete.
Netting screwed into hollow plaster, or simply weighted down with a planter, looks like protection. It gives way at the exact moment something becomes worth chasing: a bird, a fly, a noise.
If you rent, the question is not only technical. Many buildings have rules about anything fixed to the facade. That question comes before the drill, not after.
Hard floor, a wall throwing heat back, no draught when the railing is solid: an exposed balcony becomes unusable in the middle of the day while the flat itself stays mild.
Morning shade is not afternoon shade. A cat asleep in the shade at eleven can wake up in full sun, and a sleeping cat does not always move in time.
A bowl left outside evaporates, warms up and fills with dust. Empty it and refill it rather than topping it up.
A balcony cat chews whatever is within reach, more often out of boredom than appetite. The useful sort is short: lilies and their relatives have no place where a cat lives, and the rest is judged plant by plant.
What goes into the pots counts as much as the plant: slow-release feed, slug pellets, treated compost. These products are designed to be tasty or long-lasting, and neither is wanted here.
A clump of cat grass in a corner takes some of the chewing elsewhere. It is not a guarantee, it is an alternative on offer.
Reading height is learned. A cat raised in a closed flat, or taken on as an adult, has no experience of that space and no reason to distrust an edge.
The first trips outside happen with you, they stay short, and not at the hour when the street is full of new noise. You watch what it does with edges, pots and railings.
A cat that climbs onto the rail once will do it again. That is the signal that a protection is missing, not that it needs telling off.
A chair, a box, a bag of compost, a bike propped up: every object against the rail adds height at the start and demotes a decent railing to a simple obstacle.
Tidying the balcony is therefore part of securing it, exactly like the netting. A secured balcony used as a storage space becomes an ordinary balcony again.
The same logic applies to furniture against a tilt-and-turn window: the cat climbs, slips into the angled opening and gets trapped by the hips. That accident is described regularly, and it is serious.
