Step 1: Place the cat at F3
The board reaches 1/7 cats after the placement at F3.

Use this image to confirm the cat at F3, row 3, column F. This keeps the one-cat-per-row and one-cat-per-column rule intact.
- Board state shows 1/7 cats placed.
- F3 is the new cat for this step.
- 6 cats remain after this placement.
