Add I4 while keeping G3 fixed; the board diagram now shows 2/9 cats.
Use this board diagram to confirm the cat at I4, row 4, column I. Keep the earlier cats at G3. This keeps the one-cat-per-row and one-cat-per-column rule intact.
Board state shows 2/9 cats placed.
I4 is the new cat for this step.
7 cats remain after this placement.

Add B8 while keeping G3, I4, F6, D7, A2, C5, H9, and E1 fixed; the board diagram now shows 9/9 cats.
Use this board diagram to confirm the cat at B8, row 8, column B. Keep the earlier cats at G3, I4, F6, D7, A2, C5, H9, E1. This keeps the one-cat-per-row and one-cat-per-column rule intact.
Board state shows 9/9 cats placed.
B8 is the new cat for this step.
All 9 cats are now placed without sharing a row or column.

Logic recap
Why This Solves Level 123
The final placements (E1, A2, G3, I4, C5, F6, D7, B8, H9) 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 E1, A2, G3, I4, C5, F6, D7, B8, H9.
How many cats are in Meowdoku Level 123?
Level 123 uses a 9x9 board, so the answer places 9 cats.
Do I need to watch the Level 123 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.
