Cats are natural hunters, so it's no surprise they would enjoy a tactical game when it's time to eat.
Benjamin Millam, a self-described "aspiring geek," created an interesting feeding game for his cat. Instead of dumping some food in a bowl every day, he hides small plastic golf balls around his house and when his cat retrieves them and places them into a custom-made bowl, the contraption releases a small amount of food.
Millam has a full tutorial on his website, including how to train your cat, just in case you want to put your feline to work.
