In the lesson ‘Que = Whom, which, that (relative pronouns)’ an example sentence is given as:

‘La femme que je dessine’

An example sentence from this lesson is: ‘Le chat, auquel tu as fait peur’ OR ‘Le chat, à qui tu as fait peur’ 

I’m struggling to understand why is ‘Le chat, que tu as fait peur’ is not used?

Thanks

"and just as in English, you would never say "I'm going to my home""

I think saying "never" here is incorrect. I can think of situations when I might say this.
