The main goal for this game is to take care of your new cat. You feed it, play with it and let it sleep. Use the arrow keys to move. When you do this, you will get happy coins. If you get lots of happy coins you get achievements, the greatest achievement is the Crazy For A Mad Cat Lady. Also, you can get different costumes with Happy Coins, just don't click them until you have enough. (If you do it glitches and you need to reset the game to fix it. If any of the Hunger / Thirst / FUN!! / Sleep drop to 0 then you cat dies and please try better next time :(
Ummmmmmmmmmmm... thanks to cats for existing? Thanks to @HappyCat2245 for the original
