Follow the replay below. Each board shows the result after applying that step.
Meowdoku Level 680 Step 1: Mark X at R1 C4, R1 C5, and R1 C6 + 9 more: regions are trapped in those lines
Column 2 can only be filled by the sky blue region. Those region must stay in that column. Mark the highlighted cells with X.
Meowdoku Level 680 Step 2: Mark X at R9 C4, R9 C5, and R9 C6 + 9 more: regions are trapped in those lines

Meowdoku Level 680 Step 4: Mark X at R2 C2: cats cannot touch
Every possible cat for the brown region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 680 Step 5: Mark X at R9 C1 and R9 C2: cats cannot touch
Every possible cat for row 10 conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.

Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 680 Step 10: Mark X at R7 C2: assuming a cat there leaves a region empty
Suppose held a cat in the sky blue region. That assumption would leave the rose region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 680 Step 11: Mark X at R8 C2: assuming a cat there leaves a region empty
Suppose held a cat in the sky blue region. That assumption would leave the rose region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
Meowdoku Level 680 Step 12: Mark X at R10 C2: assuming a cat there leaves a region empty
Suppose held a cat in the sky blue region. That assumption would leave the rose region with no legal cell left. So cannot contain a cat. Mark it with X.
Try a temporary cat at , then follow what the puzzle rules force. If it leads to a contradiction, the must be X in the real puzzle.
