Step 1: Place the cat at E1
The board reaches 1/6 cats after the placement at E1.

Use this image to confirm the cat at E1, row 1, column E. This keeps the one-cat-per-row and one-cat-per-column rule intact.
- Board state shows 1/6 cats placed.
- E1 is the new cat for this step.
- 5 cats remain after this placement.
