When new members get added into your family, you always require a period of adjustment; no matter who you are. You might be a person or an animal. This video showcases a similar situation, where a new kitten joins a family. So the resident cat takes it upon himself to teach the little guy a few lessons.
The older cat finally accepts his fate and gives the kitten a few instructions about his new life. And everything he says makes sense. Maybe this is how our cats communicate behind our backs. This video is an advertisement for Friskies and it is one of the funniest ads I have watched.
