What makes the eyes of some animals twinkle and look like silver?

Some animals that hunt in the dark appear to have eyes that twinkle. This twinkling is caused by a substance that coats the retina and looks like silver. What's this substance called?





It's either





Retinalis


Reflectorus


Agnesis


Tapetum

Cats, like dogs and many other animals, have a tapetum lucidum, which is a reflective layer behind the retina that reflects light that passes through the retina back into the eye.What makes the eyes of some animals twinkle and look like silver?
