Solving a cat logic puzzle with one piece per color, row, and column

I wanted a short logic puzzle I could open in a browser tab, without installing anything and without a competitive timer hanging over me.

The rules I play with are simple:

- Place cats so every color, every row, and every column contains exactly one cat.

- Turn on the optional no-touching constraint when I want a tighter board.

- Use coordinates and hints only after I have already tried a placement out loud.

- Switch to night mode or colorblind mode when the default palette is harder to read.

- On a later run, swap the default cat piece for a custom image or GIF just to change how the board looks.

I have been playing Cat Puzzle Game. It is a free browser logic puzzle with tutorial levels, scoring, lives, and a multilingual UI. No install is required. It is not a deep competitive puzzle platform, but it is a clean five-minute break when I want a constraint-satisfaction problem with a lighter theme.
