A cat flap that automatically bars entry to a pet if it tries to enter with prey in its jaws has been built as a DIY project by an Amazon employee.

Ben Hamm used machine-learning software to train a system to recognise when his cat Metric was approaching with a rodent or bird in its mouth.

When it detected such an attack, he said, a computer attached to the flap's lock triggered a 15-minute shut-out.

Mr Hamm unveiled his invention at an event in Seattle last month.

The presentation was subsequently brought to light by tech news site The Verge.
