Can you elaborate on what about this is torturous? It sounds like the experimenter treats the rats well, got them acclimated to his presence/the harness/the treadmill over time, and only ran the tests with them for less than two weeks.

Well this doesn't look like "torture" to me for a start. Admittedly I don't have much knowledge of what goes on in a rat's mind but this looks uncomfortable at worst. He says in the final line: "The experiment was approved by the Feinstein Institutes’ Institutional Animal Care and Use Committee."

Clearly I don't think that simply because worse torture exists that somehow placates a rat's mind, but as a human I choose to point my outrage where it is most effective.

Also, aren't these lab rats? Where would they be had he not picked them for this experiment?
