Not that surprising Steve, a study years ago found that the smell of rat urine left in the lab from prior experiments will perturb the stress responses of mice. There is as certain unjustified confide3nce in some biomedical research because it presupposes that all the relevant variables are controlled; and this assumption is often made by those who understand very little about the sensitivity of different species to different stimuli. Very difficult to anticipate all the relevant variables.
