This game was a prototype Atari 2600 game by UA Limited that was never released. There are a few copies of it floating around, (but not many). This game has shown up under the name Cat N Mouse on a european multicart.

This game is a decent rip-off of Pac-Man. With cats and mice instead of Pac-Men and ghosts.

Prototype games like Cat Trax are the Holy Grail as far as rare Atari Games go. Nothing is harder to find than these. The value of this prototype is unknown.
