What features are best interpreted as indicators of pain or distress in rodents?

Rodents. Pain in rodents usually results in decreased activity, piloerection and an un-groomed appearance, or there may be excessive licking and scratching. They may adopt an abnormal stance with ataxia, but rats and mice may become unusually aggressive when handled. Acute pain may cause vocalization.

What normal behavior may mask whether a rat is experiencing pain or distress?

Rats and Mice* Rodents in pain generally have decreased activity, but increased activity may also be seen. Other abnormal behaviors include back-arching, belly-pressing, twitching, and staggering.

How do federal regulations address animal pain and distress in research quizlet?

How do federal regulations address animal pain and distress in research? Animal pain and distress must be avoided or minimized when consistent with sound scientific practices.

Which statement is true about body temperature in rodents?

Which statement is true about body temperature measurement in rodents? Body temperature can be used to predict death in procedures associated with high mortality.
