Also, holy shit, look at that “unpleasantly restrictive cage.”  How did they get the rats in there?  Did they stuff them in forcefully, while conscious?  Did they sedate them, so the rats awoke trapped in a tiny plastic box with no memory of how they got there?  It’s like a little rat Saw.  If rats can feel bad for other rats, we’re really gonna regret science when the rats take over.
