To examine whether @entity734 to having temperatures taken might reduce the emotional @entity221 induced by other stressors, 20 @entity35 were habituated by having three colonic temperatures taken within 6 min twice a week for 8 weeks. Two novel stressors were added during Week 9; @entity35 were given an intraperitoneal saline injection before taking their temperatures on Day 1, and on a second day, they were housed with a group of unfamiliar animals for 5 min before taking their temperatures. Temperatures during Weeks 10-11 were taken as during Weeks 1-8. Results showed that, overall, the third daily temperature averaged 1 degrees C higher than the first, indicating that taking temperatures was stressful. Between weeks, temperatures rose between Weeks 1 and 2, suggesting a conditioned @entity221 . Temperatures fell 1.5 degrees C from Weeks 2-8, indicating @entity734 . During Week 9, temperatures after the intraperitoneal injection were no higher than during Week 8; however, 5 min of group housing raised temperatures 1.5 degrees C for males and 2.5 degrees C for females. Temperatures during Weeks 10 and 11 were below those of Week 8, suggesting that the @entity221 induced by group housing in Week 9 was situation specific. These results indicate that @entity35 habituated to having their temperatures taken exhibit emotional @entity221 only to selected new stimuli. Body temperatures do not rise after an intraperitoneal injection given by a familiar handler, but briefly placing @entity35 with unfamiliar animals induces a substantial febrile response.
