Cat Enclosure Buying Guide: How to Choose (UK 2026)

By the Purr Perch editorial team · Updated 2026 · How we test & score

Choosing a cat enclosure starts with knowing which kind you need - litter-box furniture, an outdoor catio or run, or an indoor cage - then sizing and building it right for your cat. This guide walks through type, placement, size, material and setup so you pick the right one.

Type and placement

First decide the job. A litter-box enclosure hides the tray indoors as furniture. An outdoor catio, run or pop-up gives safe fresh air. A cage or pen contains a cat securely indoors (settling in, recovery, short-term). Placement follows: indoor furniture and cages for the home, weatherproof structures for the garden, balcony or patio. Get the type right and everything else follows.

Size and your cat

Size to your cat with room to spare. A litter enclosure needs internal space to enter, turn and dig - cramped ones put cats off. An outdoor run should give real room to move, climb and rest, with vertical space cats love. A cage needs room to stand, stretch and turn. Bigger cats and multi-cat homes need noticeably more; when in doubt, go larger.

Material and weatherproofing

Match the material to the placement. Wood looks warm as indoor furniture and gives shelter outdoors but needs weatherproofing (treated finish, roof) to last. Metal wire is secure and airy - good for outdoor runs and cages - and powder-coating resists rust. Fabric and mesh are light and packable for portable pop-ups but best for supervised use. Anything left outside needs to shrug off rain and sun.

Setup, security and access

For outdoor enclosures, security is non-negotiable - it must be genuinely escape-proof, on level ground, ideally connecting to your home via a cat flap or tunnel. Check what assembly is involved and whether you can lift and position it. For all types, easy access for cleaning (a fully opening top, wide doors) makes daily life much easier. Ventilation matters for litter enclosures.

Frequently asked questions

How do I choose a cat enclosure?

Start with the job - hide the litter tray, give outdoor access, or contain indoors - then size it generously to your cat, choose a material suited to the placement (wood or metal for permanent use, fabric for portable), and check security, weatherproofing and easy access. Match the enclosure to your specific need and your cat's size.

What size cat enclosure do I need?

Size to your cat with room to spare. Litter enclosures need internal room to turn and dig; outdoor runs need real space to move and climb; cages need room to stand and stretch. Bigger cats and multiple cats need more. Always measure the enclosure's internal and external dimensions against your cat and your space before buying.
