In the year 20XX, there is a huge flood of cats that have been changed by radiation. They have become magical. They can get food and shelter by meowing. They no longer need their owners. Thus, the cats began to leave humans. The humans, feeling a sense of crisis, developed a cat detector to find the hidden cats and persuade them to live with them.
The name is Neko M. Neko meaning is cat and M is meow, so it is called Neko Meow.
It has a radar that detects the faint voltage emitted by cats and locates them, and a Geiger counter that can measure radioactivity to determine if a cat is normal or not. The device, which fits in your hand, is perfect for finding cats.
This will bring life back to normal for cats and humans.
