Share the slaughter-house videos you tend to share around

Just the title but here's what prompted me to ask:

My mom is coming to visit and even tho I've made it clear I don't like non-vegan products in my house she pushes for me to let her have at least milk for her coffee. Last time she came with my brother they got something with meat delivered because I was in bed puking my guts out. When talking soon after me going vegan she said her pregnancy state felt super good so surely the cows aren't suffering that much... etc...

So I've thought of a great way to fight that back non-confrontationally and helping her understand: in order to bring a product in she has to watch a video with me. I'm hoping to watch a whole documentary during her visit but I think shorter videos would be more feasible.

Speaking of, I have never watched a whole documentary or in a very long time, didn't need them, if you had to choose one which would you choose?
