All the caves in Cat Quest are clearly visible on the map, all but one, called precisely Secret Cave.
The cave is located on a snowy islet in zone a northwest of the map, just north of Frozen Falcione, and is located under an isolated bush. You can see its exact position in the following images.
Don't be fooled by the “Level 0” indicated, the Secret Cave is a treacherous place to explore. In particular, you will have to pay close attention to where you put your feet, since on a good part of the path, lethal magical traps will be activated ready to drain your life points. Just stop before them and wait for them to dissolve by themselves. If you want to complete the cave, you will also have to take down the invisible monsters that are in the center of each trap.
Ignore the exits that you will find along the way, collect the treasures you will come across, but beware of the Mimic.
You will recognize the end of the cave when you can no longer continue and you will see at the end of the path an exit and a sphere of experience isolated from everything.
Not only is that one sphere worth 777 XP, but it actually also points to a secret passage that you will find simply by continuing to walk to its right. Keep walking on the water and you will come across three treasure chests, one of which is locked; after opening them continue to the right again and you will find yet another locked chest. Finally, at the bottom of the secret passage, you will find the very last trap that you will have to break down to complete the cave.
