Cat Trap.

You know that game, "Cat Trap"? Where you fill in tiles and trap the cat on the board? Yeah, this is that, but make it sad.

Salem, a gentle black cat, has a perfect life. Until one night, everything goes wrong. A while after that unfortunate night, he wakes up in a very odd place. He later discovers how terrifying this place truly is.

I do not own Cat Trap or the cat in the game. I only own this story, and the Marie character.
