A cat flap can give your cat more freedom, but choosing the wrong type can be frustrating. The best cat flap depends on whether your cat is microchipped, where the flap will be fitted and whether you need to stop other cats entering your home.
For many UK homes, a microchip cat flap is the most practical upgrade because it only opens for your cat’s registered chip.

Microchip vs manual cat flap
A manual cat flap is usually cheaper and simple to use, but it may allow other cats to enter. A microchip cat flap costs more but can be better if neighbouring cats are a problem.
Before buying, check whether the flap can be fitted into your door, wall or glass. Some installations may require a professional fitter.
What to check before buying
- Installation: check whether it suits wood, uPVC, glass or wall fitting.
- Microchip compatibility: important for microchip flaps.
- Size: large cats need a larger opening.
- Locking modes: useful for keeping cats in at certain times.
- Weather sealing: helps reduce draughts.
My recommendation
If other cats are likely to enter your home, choose a microchip cat flap. If you only need a simple indoor/outdoor flap and budget matters most, a manual model may be enough.
