Cat-Proofing a Flat: Windows, Balconies, Cords and the Laundry Habit

In a five-month study of 132 cats treated after falling from windows, 90% survived — but 37% needed emergency, life-sustaining care, 39% had limb fractures and 57% had facial injuries. The mean age was 2.7 years: old enough to be confident jumping at a pigeon, not old enough to stop. The term for a fall of two storeys or more is high-rise syndrome, and most of these cats did not jump. They lost footing, misjudged a gap, or rolled off a ledge in their sleep.

The Window Is the Main Event

An insect screen keeps flies out; it is not a barrier for 4–6 kg of cat arriving at speed. Three things decide whether a window is safe:

• The mesh: press it from inside with the flat of your hand, the way a cat lands on it. If it bows out of the frame or rattles, it will pop. Fibreglass and thin aluminium are the weakest; pet-screen mesh or a rigid metal guard is the fix.
• The frame: a screen held in by friction alone can be pushed out. Screw the frame into the window opening, or fit a guard rated to hold 45 kg.
• The opening: a limiter that caps the gap at 10 cm, or a mesh panel that lets the window open fully behind it. Child window guards are not enough — cats pass through gaps built to stop toddlers.

Test the screens before the first warm week and again after any storm. Furniture within two metres of a window is a launch pad; move it or accept the risk.

Balconies: Net, Anchor, Then Nothing to Climb

Netting works only if it is fixed to the structure, not to a railing a cat can push away from the wall. Mesh openings under 5 cm, tensioned at the top and bottom, with no gap at the corners — a kitten fits through a gap you would call a crack. Everything on the balcony becomes a step: a chair, a plant pot, a storage box. The order is net first, then clear the furniture, then supervised access.

The Whole Flat, as a Table

Hazard	What it does	The fix	How often to check
Window above the ground floor	Fall of 2+ storeys; 90% survive but 37% need emergency care	Rigid screen plus a limiter	Every spring, and after storms
Balcony railing	Cat goes over the top or through the gap	Anchored net, mesh under 5 cm	Monthly, corners included
Washer, dryer, dishwasher	Warm drum, closed door, no way out	Count cats, then close the door	Every single load
Cables behind furniture	Chewing causes mouth burns and fluid in the lungs	Trunking, clips, unplug what is idle	When a new device arrives
Ribbon, tinsel, hair ties	Linear foreign body; the gut pleats along it	Lidded bin, no dangling toys left out	Weekly floor check
Lilies	Pollen and leaves cause acute kidney injury	No lilies in a house with a cat	Every bouquet
Recliner, sofa bed	Crush injury when the mechanism closes	Look underneath before every fold	Each use
Plastic bags	Suffocation, panic, no air	Knot them and store them shut away	Each shopping day

Cords, and the Appliance Habit

Cats chew cables for the texture and the curiosity, and the result is burns at the corners of the mouth, drooling, and in bad cases fluid in the lungs. Route cables through trunking or behind a solid panel, and unplug what is not in use. The laundry is a separate risk with a simple ritual: open the door, look inside, count the cats, close the door. A warm dryer is the best bed in the house, and a cat that climbs in while you fold towels will not be seen. The same applies to the washing machine, the dishwasher, the fridge and the oven — and to the recliner, which folds a cat as easily as a cushion.

String, Small Things, and the One-Week Rule

Linear objects are the worst category because they are cheap and everywhere: ribbon, tinsel, dental floss, hair ties, the string on a roast. A cat that swallows 30 cm of ribbon can have its intestine pleated along it, and surgery is the fix. Never pull a visible string out of a cat's mouth or bottom; it may already be anchored. The floor rule: if it is smaller than a ping-pong ball or longer than your hand, it does not live on the floor.

Plants, Oils, Cleaning Products

Lilies matter most: leaves, flowers and pollen can cause acute kidney injury, and pollen travels on fur and clothes. Essential-oil diffusers, bleach and some "natural" floor cleaners are also on the list. Check every product against the toxicity list before it comes into the house, and keep the diffuser out of reach or out of the flat.

If It Goes Wrong

After a fall, go to a vet even if the cat walks away. Lung contusions peak 48–72 hours later, and a cat that seems fine at hour three can be struggling at hour forty. Do not give human painkillers: paracetamol and ibuprofen are both toxic to cats. If a string is visible, do not pull. If a cat has chewed a live cable, switch the power off at the breaker before touching the cat. The carrier work that makes an emergency trip possible is covered in carrier training.

A One-Hour Audit That Covers Most of It

Walk the flat at cat height: kneel, then look up at every window and down at every gap. Fix in this order — windows, balcony, laundry habit, cables, floor clutter. Repeat it once a year, and whenever a new appliance, plant or piece of furniture arrives. A new cat or kitten needs the audit twice: once before it arrives, and once a month later, when you know which surfaces it actually uses. If the cat needs the outside, a window perch or a climbing wall gives the view without the drop.
