Meowdoku Level 827 Step 11: Mark X at R8 C1: cats cannot touch
Every possible cat for the sky blue region conflicts with these cells. Cats cannot share a row, column, region, or diagonal touch. Mark the highlighted cells with X.
Meowdoku Level 827 Step 12: Mark X at R1 C5: assuming a cat there leaves a region empty
Suppose held a cat in the blue region. That assumption would leave the teal 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 827 Step 14: Mark X at R2 C5: assuming a cat there leaves a region empty
Suppose held a cat in the blue region. That assumption would leave the yellow 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 827 Step 15: Mark X at R2 C6: assuming a cat there leaves a region empty
Suppose held a cat in the blue region. That assumption would leave the sky blue 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.
