How these Catdoku guides work

Catdoku is a one-cat-per-row, column and color logic puzzle: fill the board so every row, every column and every colored patch holds exactly one cat, with no two cats touching, not even diagonally. Each chapter guide shows its techniques on that chapter's own boards and solves a few of them in full, with the deduction path written the way a person would actually solve it: smallest patches first, crossing out squares as each cat lands. Levels are identical for every player, so the boards match the ones in your game.

No level ever requires guessing. If you would rather find the move yourself, open the level in the game and tap the hint paw: it points at the row, column or patch where the next forced move hides, and only reveals the square if you ask again.
