Its 5 am. You are a cat. You are hungry but your humans are sleeping. What to do... Scratch cherished items around the house as loudly and annoyingly as possible until the humans wake up and feed you.
Be careful though. If you take too long or get sloppy they might get up and spray you instead! Green scratches are special and will give you scratch points which you can redeem to unlock new things to scratch! Circles require sticking your claws in, while long ovals require scratching. Be sure to stay in the boundaries or else you will lose time!
