The third ending is in the first level.

What is the third ending of the cat girl? Since the time of ichi, I can't figure out how to knock it out.

I belive that is the one where you escape while the catgirl is chasing you and trying to kill you. Make her mad and and leave the building whilst the chase music is playing. Hope that helps.
