Questiondo rats have an unsual eyesight????????????????????????????
AnswerYes, actually they do!!!!!!!!!!!!!!!!!!
They have very poor vision, both red eyed rats or dark eyed rats. They may sway their head back and forth in order to judge how far away in the distance an object is.
You can read about it on my website.
