Description:
First, a bit of preparation. You have two options:

1. Clicking manually – You can use both mouse and keyboard to gain CATS (the currency used to buy upgrades).
If you're using the mouse, click on the cat image.
If you're using the keyboard, you can simply spam keys. Yes, you can use both at the same time!
⠀
⠀
2. Autoclicker – You can use an autoclicker by placing it over the cat image.

The game contains two stages. The first is Earth, where you can earn 15 achievements:

If you progress to Stage 2 without unlocking all Earth-exclusive achievements, don't worry—after buying a certain upgrade in Stage 2, you’ll be able to return to Earth.

After purchasing the God Cat upgrade, your cat counter will change to show progress like this:
Current cats / 100,000,000
To reach Stage 2, you need to collect 100 million cats after buying the God Cat upgrade.

Once you've done both, an envelope will appear on-screen. Click it several times to open it. Inside, you'll receive a letter with an "Accept" button. After clicking it, you'll meet Gorge, the current president of the cat planet, who will explain the situation and your new goal.
⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

If you prefer to skip the dialogue, you can choose the second dialogue option to skip the story part entirely.

After speaking with Gorge, you will notice three new buttons appear in the top-right corner under the Options button:

1. Ranking Button
This shows the planet ranking based on human population.
You will also see an option to pay off debts (this is optional).
Every 5 minutes, cat planets will randomly increase or decrease their human population by 2%.

2. Info Button ("i")
This button displays stats such as:

• How many Cat Rain events you've triggered
  
• How many Cat Coins you’ve clicked
  Other information here is not particularly important.

3. Human Shop Button
This is where you collect and spend humans.
The first row of upgrades in the shop is critical:

• Upgrade 1: Allows you to travel back to Earth (Stage 1)
  
• Upgrade 2 & 3: Unlock the final two upgrades in Stage 2
  
• Upgrade 4: Doubles the bonus amount humans give you

You can obtain humans by:

• Earning 100k cats per 1 human
  
• Buying upgrades

⚠️ Important:
After collecting humans, your Stage 2 progress will reset, so plan carefully!

There are 17 achievements available in Stage 2.
This includes the 2 cross-stage achievements: Lucky One and Collector.

The last 3 achievements in the game are tied to how many different cats you have collected.
Each collected cat provides bonuses at the start of your next playthrough (after collecting humans).
You can view your cats by hovering over them in the Inventory menu.



How do drops work?
The drop system is triggered at the start of the game, then again:

• 5 minutes after starting
  
  • Once every 8 hours afterward
    
  • You can obtain up to 2 cats every 8 hours
• There are currently 17 cats in the drop pool
  
• You can view the drop pool by clicking the "?" button in the Inventory menu
