But the only way to find out that the experiment is sensitive to specifics of some animals is to run it with different animals in the same laboratory.
If the original paper finds a result and I fail to find the same result with different animals, I have no way of knowing if the difference is because of my animals or some other small difference in experimental setup -- unless the experimental setup is explained in enough detail in the original paper.
