🖼 A hidden picture is waiting inside the grid. Use the numbers above each column and beside each row to work out which squares to fill in — the answer key sits at the bottom, fold it backward along the dotted line before you start.
A logic-grid picture puzzle (also called picross or griddlers). Use the number clues to fill in the correct squares and reveal the hidden image.
Each number tells you how many squares in a row to fill in that line, in order. A clue of 2 2 means: fill 2 squares, leave at least one blank, then fill 2 more.

How to Solve This Nonogram
Nonograms (also called picross, griddlers, or hanjie) are logic puzzles that hide a picture inside a grid of numbers:
Fill the long horizontal body first. The middle rows carry big single runs like 21 and 20 across the 25-wide grid. That solid horizontal bar is the cat's body — lay it down first and everything else hangs off it.
Use the repeating leg pattern at the bottom. The lowest rows all read the same: 3 2 2 2. Those four separate blocks are the four legs with gaps between them, so once you spot the pattern the legs almost place themselves straight down.
Trace the raised tail on the left. The upper-left rows show short climbing runs (a 2, then a 4, then a 5) that curl upward. That is the tail lifted high — follow the clues up and let it hook back over the cat's back.
Not sure where to begin? Here's exactly how Mr. Puzzle opens this grid. Rows are numbered top to bottom and columns left to right.
Clear the border. Rows 1, 2, 24 and 25 have no clue, and neither do columns 1 and 25. The working area is columns 2 to 24, which is 23 squares wide.
Rows 12 and 13. Row 12 (21) has 2 squares of wiggle room, so columns 4 through 22 are filled. Row 13 (20) has 3, so columns 5 through 21.
Rows 11 and 14. Row 11 (3 17) has 2 squares of wiggle room in total. The 3 always covers column 4, and the 17 always covers columns 8 through 22. Row 14 (18) gives you columns 7 to 19.
Column 18 (17). In a working height of 21 rows (3 to 23), that's 4 squares of wiggle room, so rows 7 through 19 are filled.
Stuck? Click for a nudge
The bottom four rows all have the same clue (3 2 2 2). Whatever you work out for one of them applies to all four.
Why It's Rated Hard
It's a big 25×25 shape with a lot going on: a raised piece on the right, a separate part in the upper left, and four thin columns at the bottom. No guessing, but plenty of crossings to keep track of.
Spoiler: what does this puzzle hide?
Professional Mouser shows a cat in mid-stride, side profile, tail raised high with a confident curl — the classic look of a cat on patrol. This 25×25 Hard puzzle leans on pattern-spotting: the long body rows and the repeating four-leg clues give you a strong framework, while the lifted tail on the left is the flourish that finishes the picture. A rewarding solve with a bit of feline attitude.
