Easy cat sudoku is a 6×6 grid. One cat in each row, column, and color, and no two cats touch.
A short grid for the first rules
Easy cat sudoku has six rows, six columns, and six colors. It is the right size for learning which squares a cat rules out: the rest of the row, the rest of the column, the rest of the color, and every square touching the cat.
When that feels small, move up to hard 9×9 boards.
