Step 1: Place the cat at C1
The board reaches 1/6 cats after the placement at C1.

Use this image to confirm the cat at C1, row 1, column C. This keeps the one-cat-per-row and one-cat-per-column rule intact.
- Board state shows 1/6 cats placed.
- C1 is the new cat for this step.
- 5 cats remain after this placement.
