We have red eye, cats have green eye?

Hi everyone, I was really surprised when I opened this picture, I have not changed or edited it except to make it a bit smaller. I have never seen green eye before and do not understand it. I was told red eye was caused by the camera flash going through the transparent eye and lens and showing the red (from blood vessels) at the back of the eye. If this is true, why has my cat got 'green eye'.
Have any of you with photos of your cats had 'green eye'?

Yes, loads of them. Cats eyes are optimised to work in very low light, so the backs of their eyes reflect and collect different wavelengths of light. Hence the green colour when you shine a light in their eyes. Dogs eyes do something very similar.

Any cat carrying the Siamese Blue Eyes gene will have the same redeye as a human due to depigmentation of the back of the eye - just to confuse matters. ;)

Well now, this could be a photography project in itself - any other interesting results from other animals we can think of?

"The color of the eyes in the picture also depends on the angle at which you take a photo. Taking pictures of the same animal from different positions of your camera may produce different results:"

Hi and welcome to moblog

Beth - Aha! I took some shots of Misha's kittens some time ago where some of their eyes were different colours. Thought it was a problem with my photography at the time...

Yep, cats have 'green eye'. Rats have 'blue eye'. Interesting stuff. :) Welcome to Moblog!
