A cat's eyes dilate when they feel stress or excitement, as well as to see better at night. How much better is feline night vision than that of humans?

We lose the night vision contest because cats have 6 to 8 times more rod cells, the cell type most sensitive to low light. Along with frogs and owls, cats also have a special mirror-like layer called the tapetum lucidum that reflects light back out (and also is the reason why your kitty's eyes seem to glow in the dark).
