Window perches and wall shelves for cats

A cat measures territory in three dimensions. A 40 m² flat with nothing above waist height is a small flat. The same flat with two good climbing routes is not.

Why height matters so much

Height gives a cat three things at once: a view, safety from being approached from above, and a way to be present without being in the middle of things. In multi-cat homes it is also the main way conflicts get resolved without a fight — a cat that can go up does not need to stand its ground.

Window perches

If you only add one thing, add this. A window is the closest an indoor cat gets to television.

Pick the window with the most going on — a tree, a bird feeder, a street. A blank wall opposite is not worth the perch.
Sun matters. South-facing wins almost every time.
Height: just below the sill, so the cat looks out rather than up.
Suction-cup perches work on clean glass but check them weekly. For a heavier cat, a shelf bracketed into the wall or a cat tree next to the window is safer.
Add a blanket. Cats sit longer where it is soft.

If the window opens, and you are above ground level, fit a screen. Cats fall from windows more often than people expect, and "cats always land on their feet" is not a plan.

Wall shelves as a climbing route

The point is not a shelf — it is a route. Isolated shelves get ignored; a path from floor to ceiling gets used all day.

Spacing: 30–40 cm vertically between steps, staggered left and right so the cat zig-zags up. More than about 45 cm becomes a jump rather than a step, and older cats will stop using it.
Depth: at least 23 cm, wider at the top so there is somewhere to lie.
Grip. Bare varnished wood is slippery. Carpet tiles, sisal, or a non-slip mat cut to size.
Two ways down. A route with a single exit is where one cat corners another. Always give a second descent.
Fix into studs or use proper wall anchors. A shelf that shifts once will never be used again.
Start low. A route that begins on top of a bookcase the cat already uses gets adopted immediately.

Cheap versions that work

Clear the top of a wardrobe and put a blanket on it.
Move a bookcase next to the window and clear the top two shelves.
A sturdy stool beside the sill turns an unreachable window into a perch.
A cardboard box on top of a cupboard — enclosed and high at once, which is a cat's favourite combination.

Older cats Arthritis is common and under-diagnosed in cats over about ten. If a cat that used to jump up stops doing it, add intermediate steps rather than assuming it has lost interest — and mention it to the vet.
