Advancements

The mod has its own advancement tab. Its root is given without a toast as soon as any cosmetic is in your inventory. The six advancements below each pop up a toast and are announced in chat.

• First Meow: press the meow key, Z by default.
• Herding Cats: meow with five or more cats or ocelots within 8 blocks. The House Cat set helps: in it, cats within 10 blocks walk after you.
• Full Neko: wear ears, a tail, a collar and paws at once.
• Nine Lives: land on all fours nine times without taking damage. A landing counts when you wear the Alley Cat set and fall from 4 to 10 blocks. The nine don't have to be in a row, and the advancement shows the progress.
• Box Enjoyer: sit in a Cardboard Box.
• Catnip Overdose: eat Catnip while the Catnip effect from the last one is still on. The effect lasts 30 seconds, so two in a row do it.

Nine Lives the advancement and Nine Lives the effect are two separate things. The effect comes from a Cat Spirit and cancels one death.
