Add D6 while keeping C4 fixed; the board diagram now shows 2/9 cats.
Use this board diagram to confirm the cat at D6, row 6, column D. Keep the earlier cats at C4. This keeps the one-cat-per-row and one-cat-per-column rule intact.
Board state shows 2/9 cats placed.
D6 is the new cat for this step.
7 cats remain after this placement.

Logic recap
Why This Solves Level 77
The final placements (I1, G2, E3, C4, F5, D6, B7, H8, A9) cover 9 rows and 9 columns exactly once. Each cat stays inside the 9x9 board and keeps the row, column, and no-touching rules intact.
Final check
Rows 1-9 each contain one cat.
Columns A-I each contain one cat.
No two final cats touch, including diagonally.

Practice Cat Logic Without Breaking Your Flow
Meowdoku blends Sudoku-style row and column logic with colored regions: place one cat in each region, and never let two cats share a row, share a column, or touch.
If ads or limited hearts interrupt your solving flow—or you simply want X marks and help tools close at hand—play the same style of cat logic on our original original practice boards.
The final cat positions are I1, G2, E3, C4, F5, D6, B7, H8, A9.
How many cats are in Meowdoku Level 77?
Level 77 uses a 9x9 board, so the answer places 9 cats.
Do I need to watch the Level 77 video?
No. The written steps and board diagrams show the complete answer path. The video is only an optional reference.
Is this an official Meowdoku level guide?
No. This is an unofficial independent guide that explains the logic for players. It is not affiliated with the official Meowdoku app or its developers.
