“Openable door” just means a door that swings rather than slides: hinged patio doors, French doors, single back doors, villa kitchen doors. All of them can take a cat flap, but some make better candidates than others.
Here is a quick comparison to help you pick the right door in your home. Whatever you choose, it falls under cat flap installation for hinged patio doors.

Hinged patio doors
The classic choice. Large lower glazed panels give plenty of room for the flap, and the panel-swap method keeps everything neat. Best when the door opens onto a terrace or garden your cat can use.
French doors
Elegant and practical. The flap goes in the passive door’s lower panel, leaving your main door untouched. Ideal for living rooms opening onto patios in villas and townhouses.
Single swing doors
Simple and direct. Kitchen and utility doors, often wood, take a flap with a straightforward cut. Great as a secondary route when the patio door is not suitable.
What makes a door a good candidate
- Cat-height panel space. There must be room for the flap at your cat’s belly height.
- Safe landing zone. The other side should open onto a secure terrace, garden, or room, not a road.
- Clear of locks and handles. The flap position must not clash with the door’s hardware.
Once fitted, sealing matters as much as placement: read how to seal the gaps around a patio door cat flap.
