abnormal sensory capabilities/reflexes/nociception ( J:173325 )
• display a reduced aversive response and decreased innate avoidance behavior to the predator odorant TMT, a component of fox feces
• however, the responses to 2MB acid, an odorant of spoiled food, are similar to controls
• mice can be conditioned to respond to TMT indicating there is not a defect in detection of this odorant
