Find the cats - Cat Sudoku!

Catdoku is a calm logic puzzle about finding hidden cats on a colorful board.

Each puzzle follows three simple rules:
- Each color region hides exactly one cat.
- Each row and column can contain only one cat.
- Cats cannot touch, even diagonally.

Mark impossible cells, place cats when you are sure, and use contextual hints when you want a nudge. The game is designed for short, focused sessions with friendly feedback, clean visuals, and satisfying puzzle progression.

No math is needed. Just observe the board, eliminate impossible cells, and find every cat.
