This is a program run by itself; it doesn't have any control and won't influence by anyone. Each tick (1/10 second), a cat have 50% chance of replicating itself; it'll die after 2 ticks. The program spawns 50 cats at the start. The CLONES varible shows how many cats are there at the time; AVG CLONE represents how many of cats on average from the start of the simulation; Total Clones represents how many cats have been spawned; Cat: frame shows how many frame has passed from the start; last reproduction shows how many cats has been spawned in the last 2-frame period. The cats' colour represents the generation the cats are on.
