Frequently Asked Questions (FAQs)

1. Are magnetic cat flaps any good?

Magnetic cat flaps work, but they damage a cat's collar so much that they rarely last more than a couple of days! This is why cat owners all over the country - and the world for that matter - place the safety of their cats and their homes in the capable hands of microchip cat flaps.

2. Can burglars get through cat flaps?

Adding a cat flap to a door immediately weakens it but the greatest issue is it can allow burglars to reach in and hook things like keys out with a tool or even found object such as a garden cane.
