In darkness with a torchlight, head lamp or other light. When the source of light is held close to the eyes of the observer, the tapetum lucidum in the eyes of the animals (reflecting layer of cells behind the retina) causes a reflection well visible as long as the animal is looking towards the light. The tapetum causes light rays to cross the retina twice and probably shifts ultra-violet light into visible wavelength for better vision in darkness. It occurs in many nocturnal and some diurnal and crepuscular species.

That's fascinating, I've always wondered why my dog and cats eyes did that.

I am extremely sorry. I just cannot keep a big list of friends. For the last one week, I simply said NO to more than 50 mylotians who wish to be my friends. The reason being, all mylotians are my friends. Why another inner circle. Even if you do not answer my question it is ok. Strictly NO for friendship circle of mylot.
