First, to unlock this, you will need to find two special cats in the Advanced difficulty search: Cacau & Ghost Cat.

Cacau is a normal looking cat that will always be in the same spot. If you find the Smelly Cat Caffè in the bottom row of building, directly left of the building lined up with its roof. You should see a cat laying next to a plant.

Clicking it will unlock:


Ghost Cat is a special cat that moves and is not always on the screen, so you may have to wait a little for it to appear. It should aways float across the bottom row of buildings, so wait there and keep a lookout for it.
The screenshot below shows the cat colored in right after I found and clicked it:

Finding both will unlock the City's Park bonus level to select in the menu.
