First you name the cat The comb is for happiness, so is the ball of yarn, the pail of water for thirst, and cat food for hunger. The arrow keys are for mini games. Both mini games are for happiness. To keep your cat alive, you need to keep the happiness, thirst, and hunger above zero!
Kittycutie6 for original project. I just remixed this so I could change the character to a pet I bought from narwhalsnakefan909.
