Sure, here's a step-by-step guide on how to play Hidden Cats: Detective Agency:

When you start the game, you will be presented with a scene filled with various objects and furniture.

Your goal is to find all of the hidden cats in each scene. The cats may be hiding behind or inside objects, or they may be partially obscured by other items.

To find a hidden cat, simply click on the cat when you see it. The cat will then be revealed and you can move on to finding the next one.

As you progress through the game, the scenes will become more complex and the number of hidden cats will increase. You will need to use your observation skills to spot all of the cats.

The game also includes a timer that counts down as you search for the hidden cats. You will need to find all of the cats before the time runs out to advance to the next level.

If you get stuck, you can use special tools such as a magnifying glass or a hint button to help you find the hidden cats more quickly.

As you complete levels and find more cats, you will have the opportunity to upgrade your detective skills and equipment. This will help you find the hidden cats more easily and quickly, and may also unlock new levels and scenes.

The game ends when you find all of the hidden cats in the final scene. Your final score will be based on the number of cats you found and the time it took you to find them.

And that's how you play Hidden Cats: Detective Agency! Keep in mind that the game may have additional features or variations depending on the specific version you are playing.
