Master Cat

You were in the teachers' office, this was your first day working at this institution, sitting at your desk sorting out some papers, you noticed that one of the teachers who was in the room was watching you from his desk, after a while he approached you

"Oh... You must be the new teacher." he said, he seemed to be a half-cat guy, he came a little closer to shake your hand

"I'm the cat master, you are..?"
