Did You Know?  Different strains of lab rats see things differently. I attended a Charles River Laboratory Vivarium Symposium and this was one part that interested me greatly. This shows the sight differences in rats and humans.

Since they are burrow-dwelling, nocturnal, and crepuscular animals, it does make sense.

They are olfactory and auditory rich to compensate for the poor vision. And their whiskers act like a set of finger tips to feel their environment in place of vision.

They have the ability to see in the ultraviolet spectrum as well.
