This is a mathematical data of both cats having a 1/2 chance to be done. If they get done, they start off again with another 1/2 chance. If the 1/2 chance does not work, then they are given a 1/3 chance, then a 1/4, 1/5, ect... Both cats are the same test, the lists are the stages they got to, (e.x. if they got to 1/5, it says 5) the one at the top is the highest it has been up to. You can set the "step" with the buttons, the speed with the bar (and turbo mode), and clear the lists with the clear button.
I did this out of curiosity. This shows that how far you climb up, it will get harder to get a "done" but statistically, you will get a "done" at some point. This is also kinda like Zeno's paradox: https://en.wikipedia.org/wiki/Zeno's_paradoxes
