Click on the cats to feed them and have kids! The cats get bigger when they become parents. The zero point button sets your coordinates to (0, 0). Use arrow keys to travel the world and if you want to go slower when traveling you can also use the "L", "R", "U" and "D" keys, which stand for left, right, up and down. If the project starts to glitch or your cats are no longer reproducing but are still getting larger then turn off replenishment mode and then take a minute to collect apples to reduce the lag.
