Catio ideas for small gardens, terraced houses and side returns

Start with the space you actually have

Many terraced houses have a small yard, a side return beside the kitchen extension, or a strip of patio under a back window. These spaces suit catios well, because they are already enclosed on one or two sides by walls, which cuts the amount of mesh and timber needed.

Measure the depth from the house wall, the length you can spare and the height to any windows, gutters or downpipes. Note where the sun falls during the day, where drains and inspection covers are, and which bits of the yard you still need for bins, bikes or drying washing.

Layouts that work in small spaces

These sizes are typical starting points rather than minimums. The real test is whether the cat has room to move, climb and get away from anything that worries it.

Going vertical

Cats use height far more than floor space. In a narrow catio, fix shelves or platforms in a staggered zigzag up one wall, with a final high perch looking out over the garden or street. Leave at least one wide, flat shelf as a lounging spot, and add a ramp or steps for older cats.

• Stagger shelves so the cat can jump in short hops
• Make shelves at least 25 to 30 cm deep
• Use slatted or textured tops for grip in the wet
• Keep the top perch clear of the roof so the cat can sit up
• Leave the floor open for a litter tray, water and bed

Access options for terraces

The simplest route is a cat flap in the back door that opens directly into the catio. Where the back door opens into a kitchen you use a lot, a flap fitted in a lower window pane by a glazier or a window box joined to the catio by a mesh tunnel can work. Sash windows in older terraces can sometimes be fitted with a slim insert panel holding a cat flap, which can be removed later.

Think about which room the cat will come and go through, and keep food and water away from the flap so outdoor smells are not mixed with mealtimes.

Things to watch in older properties

• Soft or crumbling brickwork, which needs suitable fixings and sometimes repointing first
• Airbricks and vents, which must stay clear for ventilation
• Downpipes and gullies, which need access for clearing
• Neighbouring walls, which you should not fix to without agreement
• Rear windows of neighbours, where a tall enclosure may feel overbearing

In conservation areas or listed buildings, extra controls can apply to changes to the outside of the house, so check before committing to anything fixed to the walls.

Small-space finishing touches

Paint or stain the catio to match fences or window frames so it blends in. A planted trough along the front softens the look from the house, and a part-solid roof gives a dry spot for the cat and stops the yard feeling like a cage from upstairs windows.

Keeping the yard usable for you

The biggest worry in a small garden is losing the space for people. A few design choices keep the yard working for the whole household.

• Build the catio along the wall you use least, often the shady side
• Use a hinged or removable panel so bins or a bike can be moved through when needed
• Fit the litter tray inside a covered corner so it is not on show
• Leave the top of a lean-to free for a planter or herbs on your side
• Choose mesh rather than solid panels where you want to keep a view through
• Plan the door so it opens without blocking the back door or path

In a very small courtyard, a tall cabinet-style catio in one corner may give the cat more than a long, low run would, while leaving the rest of the paving clear for a table and chairs. A window box combined with a modest ground-floor enclosure is another option, with a mesh tunnel linking the two so the cat has a choice of spots without taking over the whole yard.
