GridMew6×6 cat logic puzzles
Original puzzles, ready for a little quiet thinking.
This collection contains 80 original 6×6 boards. Each has 6 connected regions and needs 6 cats. The middle-sized grid offers space for regional locks without the cell count of an 8×8. Size and difficulty are separate: all three reasoning groups are available in this collection.
Difficulty reflects the reasoning, not just the board size.

Use the extra space to follow relationships
The 6×6 collection adds another row, column and region while retaining the one-cat quota. A deduction near the bottom may settle a column at the top. Track the whole line instead of treating nearby colored patches as separate mini-puzzles.
A useful comparison is a placement cascade versus a reservation chain: both can lead to a unique answer, but the second begins by removing options rather than putting down a cat.
