Let's say you are building a better mousetrap, but someone in your focus group either lives in an area without a
rodent problem or happens to
keep mice as pets, their feedback is not going to offer much insight.
Captive
rodents that are
kept caged and not given anything to play with or to chew on commonly develop behavior
problems including barbering (chewing hair off themselves), repetitive behaviors (such as cage bar chewing, jumping, digging, and running in patterns), fighting, cannibalism (of their mates and babies), and repetitive teeth chattering.
