SureFlap – Microchip Cat Flap
The SureFlap is a hi-tech cat flap that recognizes the ID chip already implanted in your cat, allowing access to your pet while unwanted visitors won’t be able to get in.
Your home becomes a secure environment for your pet, leading to a happier, more relaxed animal. No need for a collar or tag which can get lost or even worse caught on branches, etc.
Here’s a video demonstration of the SureFlap cat flap:
