Start Level 109 from the confirmed cat at F7.
Before any earlier pictured placement, no used row or column excludes another cell from this color region, while the no-touch rule adds no further region exclusion. The region containing F7 is left with F7; row 7 still allows A7, B7, C7, D7, E7, F7, G7, and H7, and column F still allows F1, F2, F3, F4, F5, F6, F7, and F8. The region consists only of F7, so its cat must be placed there.
Candidate scope — color region: F7; row 7: A7, B7, C7, D7, E7, F7, G7, and H7; column F: F1, F2, F3, F4, F5, F6, F7, and F8.
Exclusion rules — used rows/columns remove 0 cells from the region; orthogonal/diagonal no-touch adds 0 cells.
Forced conclusion — F7 is the color region's only legal cell.

Step 2: Place the cat at G5
G5 is the only legal cell left in its color region after the earlier placements remove every alternative.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add G5 while keeping F7 fixed; the board diagram now shows 2/8 cats.
With F7 already fixed, no used row or column excludes another cell from this color region, while the no-touch rule adds no further region exclusion. The region containing G5 is left with G5; row 5 still allows A5, B5, C5, D5, E5, G5, and H5, and column G still allows G1, G2, G3, G4, and G5. Only G5 remains in the required color region, so the placement is forced.
Candidate scope — color region: G5; row 5: A5, B5, C5, D5, E5, G5, and H5; column G: G1, G2, G3, G4, and G5.
Exclusion rules — used rows/columns remove 0 cells from the region; orthogonal/diagonal no-touch adds 0 cells.
Forced conclusion — G5 is the color region's only legal cell.

Step 3: Place the cat at D8
D8 is forced by contradiction: treating it as empty leaves the color region covering G1, H1, and H2 without a legal cell.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add D8 while keeping F7 and G5 fixed; the board diagram now shows 3/8 cats.
With F7 and G5 already fixed, used rows or columns exclude B7, C7, D7, G7, F8, and G8 from this color region, while the no-touch rule additionally excludes E8 by orthogonal or diagonal contact. The region containing D8 is left with D8 and H8; row 8 still allows A8, B8, C8, D8, and H8, and column D still allows D1, D2, D3, D4, D6, and D8. Rejecting D8 forces H8, after which the color region covering G1, H1, and H2 has no legal cell. Therefore D8 must contain the cat.
Candidate scope — color region: D8 and H8; row 8: A8, B8, C8, D8, and H8; column D: D1, D2, D3, D4, D6, and D8.
Exclusion rules — used rows/columns remove 6 cells (B7, C7, D7, G7, F8, and G8) from the region; orthogonal/diagonal no-touch adds 1 cell (E8).
Forced conclusion — rejecting D8 forces H8 and empties the color region covering G1, H1, and H2.

Step 4: Place the cat at C2
C2 is forced by contradiction: treating it as empty leaves the color region covering E2, E3, and E4 without a legal cell.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add C2 while keeping F7, G5, and D8 fixed; the board diagram now shows 4/8 cats.
With F7, G5, and D8 already fixed, used rows or columns exclude 9 cells, including D1, F1, D2, F2, G2, and D3 from this color region, while the no-touch rule adds no further region exclusion. The region containing C2 is left with E1 and C2; row 2 still allows A2, B2, C2, E2, and H2, and column C still allows C1, C2, C3, C4, and C6. Rejecting C2 forces E1, after which the color region covering E2, E3, and E4 has no legal cell. Therefore C2 must contain the cat.
Candidate scope — color region: E1 and C2; row 2: A2, B2, C2, E2, and H2; column C: C1, C2, C3, C4, and C6.
Exclusion rules — used rows/columns remove 9 cells (D1, F1, D2, F2, G2, and D3 among them) from the region; orthogonal/diagonal no-touch adds 0 cells.
Forced conclusion — rejecting C2 forces E1 and empties the color region covering E2, E3, and E4.

Step 5: Place the cat at E4
E4 is forced by contradiction: treating it as empty leaves the color region covering E2, E3, and E4 without a legal cell.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add E4 while keeping F7, G5, D8, and C2 fixed; the board diagram now shows 5/8 cats.
With F7, G5, D8, and C2 already fixed, used rows or columns exclude E2, E5, F5, F6, and G6 from this color region, while the no-touch rule adds no further region exclusion. The region containing E4 is left with E3 and E4; row 4 still allows A4, B4, and E4, and column E still allows E3 and E4. Rejecting E4 forces A1 → H3, after which the color region covering E2, E3, and E4 has no legal cell. Therefore E4 must contain the cat.
Candidate scope — color region: E3 and E4; row 4: A4, B4, and E4; column E: E3 and E4.
Exclusion rules — used rows/columns remove 5 cells (E2, E5, F5, F6, and G6) from the region; orthogonal/diagonal no-touch adds 0 cells.
Forced conclusion — rejecting E4 forces A1 → H3 and empties the color region covering E2, E3, and E4.

Step 6: Place the cat at A1
A1 is the only legal cell left in its color region after the earlier placements remove every alternative.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add A1 while keeping F7, G5, D8, C2, and E4 fixed; the board diagram now shows 6/8 cats.
With F7, G5, D8, C2, and E4 already fixed, used rows or columns exclude C1, A2, B2, C3, C4, and D4 from this color region, while the no-touch rule additionally excludes B1 and B3 by orthogonal or diagonal contact. The region containing A1 is left with A1; row 1 still allows A1 and H1, and column A still allows A1, A3, and A6. Only A1 remains in the required color region, so the placement is forced.
Candidate scope — color region: A1; row 1: A1 and H1; column A: A1, A3, and A6.
Exclusion rules — used rows/columns remove 6 cells (C1, A2, B2, C3, C4, and D4) from the region; orthogonal/diagonal no-touch adds 2 cells (B1 and B3).
Forced conclusion — A1 is the color region's only legal cell.

Step 7: Place the cat at B6
B6 is the only legal cell left in its color region after the earlier placements remove every alternative.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add B6 while keeping F7, G5, D8, C2, E4, and A1 fixed; the board diagram now shows 7/8 cats.
With F7, G5, D8, C2, E4, and A1 already fixed, used rows or columns exclude 16 cells, including A3, A4, B4, A5, B5, and C5 from this color region, while the no-touch rule adds no further region exclusion. The region containing B6 is left with B6; row 6 still allows B6, and column B still allows B6. Only B6 remains in the required color region, so the placement is forced.
Exclusion rules — used rows/columns remove 16 cells (A3, A4, B4, A5, B5, and C5 among them) from the region; orthogonal/diagonal no-touch adds 0 cells.
Forced conclusion — B6 is the color region's only legal cell.

Step 8: Place the cat at H3
H3 is the only legal cell left in its color region after the earlier placements remove every alternative.
Region 1Region 2Region 3Region 4Region 5Region 6Region 7Region 8
Add H3 while keeping F7, G5, D8, C2, E4, A1, and B6 fixed; the board diagram now shows 8/8 cats.
With F7, G5, D8, C2, E4, A1, and B6 already fixed, used rows or columns exclude 8 cells, including G1, H1, H2, G4, H4, and H5 from this color region, while the no-touch rule adds no further region exclusion. The region containing H3 is left with H3; row 3 still allows H3, and column H still allows H3. Only H3 remains in the required color region, so the placement is forced.

The completed Level 109 visual board: A1, C2, H3, E4, G5, B6, F7, and D8.
Logic recap
Why This Solves Level 109
The final placements (A1, C2, H3, E4, G5, B6, F7, D8) cover 8 rows and 8 columns exactly once. Each cat stays inside the 8x8 board and keeps the row, column, and no-touching rules intact.
Final check
Rows 1-8 each contain one cat.
Columns A-H 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 A1, C2, H3, E4, G5, B6, F7, D8.
How many cats are in Meowdoku Level 109?
Level 109 uses a 8x8 board, so the answer places 8 cats.
Do I need to watch the Level 109 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.
