Why are my cats eyes always reflective?
A cat’s glowing eyes are caused by incoming light reflecting off what’s called the tapetum lucidum — Latin for “shining layer” — explains Cat Health. The tapetum is a layer of reflective cells; light bounces off it and reflects back to the cat’s retina. This creates the appearance of a glow.
