Which three cats did Mr fogg test?

There is catnip in the abandoned study room of Mist Detective Biochemical Cat. Take it to the oil drum to bake catnip. In the innermost part of the study, there is a place in the lower right corner, where you can find a drawing on how to test the biochemical cat. That place is the study. Turn into a black cat and look for it. In that map, after finding mint, the cat that needs to play the piano will catch the ball and lead the cat down to roast.
