That's important because, even though it seems some animals were put at a slight risk, the assault many animals appear to take here is quite violent and repulsive.

Humans are animals.
We are dogs. I didn't want to wallow in this for 90 minutes. I thought I got it. I'm glad I was patient. I will not lie.
