Cats have a habit of getting into cozy places and cramped places. Limited space provides them with safety. In the game Cat Stack Adventure, cats managed to fill tall transparent containers that looked like flasks. Each can accommodate four cats. Your task is to sort the cats so that, as a result, you can place four identical cats in containers. In the game Cat Stack Adventure you will find hundreds of levels and pure pleasure from cute cats, without time limits. Just enjoy the process and think a little.
