We were very surprised when we took these pictures and saw this amazing blue color in Penny's eyes. It's the same phenomenon cats are known for. The part of an animal's eye that causes this is called the "tapetum lucidum". It reflects light so that their eyes get a second chance to absorb it.
Apparently a lot of animals exhibit this. Not people, though. The "red eye" in people-photos is simply caused by the blood vessels in our eyes. However, the red you see in the owl below is actually the tapetum lucidum.
