Reply to comment by AbouBenAdhem in Is the eyesight of small animals like mice and snakes as poor as ours would be if our retinas were the size of theirs? by AbouBenAdhem

Cats have better night vision because of a reflective layer at the back of the eye that means light hits their retina twice. Or am I thinking of dogs? Or is it the same

That layer is called the tapetum lucidum, and helps with sensitivity, but comes at the cost of resolution, making their vision blurrier than it otherwise would be.
