Click the Cat! "so simple, yet so addictive" Original project by JaxRacer
I changed it so you can hold your mouse down and not have to keep on clicking, so you can cash in things you bought (it takes away 1 of the thing you sold, it takes away the cat per second you earned from it, but it does give you back the cats you used to pay for it), and it gives you one-tenth of your cats per second every tenth of a second.
