If there's a continuous flashing red light on your PetSafe electronic cat flap even after changing the batteries, the device might be indicating an error or issue. Besides battery problems, the cat flap may experience issues due to a dirty or blocked sensor, or a mechanical fault within the lock itself. You can try to clean the sensor, but if it still continues flashing and not locking, it could suggest an internal problem which may require a professional to look at. It's always important to get any issues assessed by a qualified person to ensure both the safety of your furry friend and the longevity of the product.
