Here's how this works. Each cat is born with a set of traits. each trait makes every cat a bit different. moving costs energy. the energy usage formula is speed + size / 5 / 4 if a cat touches food it restores its energy and then uses some to spawn a new cat. cats will turn towards food if they see it. a cat will die of old age after 30 to 35 secounds of living
I made this in 2 hours lol. i can add more tho.
