It’s what you think it is, and it happens to more than just mice. I toured a bioengineering lab where they were actively severing the spines of chimpanzees to perform fiber rerouting experiments. I think the normal citizen never thinks much if at all about this kind of thing because they’re never exposed to it. A few researchers have opened up to me personally about their personal psychological trauma caused by involvement with animal experimentation. A couple PhD candidates I know changed fields entirely. One to ecology and another to environmental engineering. I personally moved forward with bioinformatics.

Edit: that isn’t to say that this result isn’t exciting for human welfare. We’ll see if it translates…
