This machine learning-assisted cat door keeps kitty from bringing furry surprises home

Using an Arduino, a bunch of code and a little machine learning, Benn Hamm created a cat door to keep his cat from bringing dead–and sometimes live–rats and birds into his home in the middle of the night. It's not often that I'm down with bringing surveillance technology into homes but, as a former cat owner who's had to clean bird shit off a flat-screen TV, I have nothing but love for this project.
