Step 1: Place the cat at B5
The board reaches 1/7 cats after the placement at B5.

Use this image to confirm the cat at B5, row 5, column B. This keeps the one-cat-per-row and one-cat-per-column rule intact.
- Board state shows 1/7 cats placed.
- B5 is the new cat for this step.
- 6 cats remain after this placement.
