No cats were harmed in making them.
Yes, Cats eyes, are 'cats eyes' although their eyes aren't the same as maybe the marble 'cats eye', only in bright light- i suppose they are just eyes though
You cannot see cats eyes unless the light catches them, when the light does you will see a glimse of glowing grees. I looks quite spooky when you see my cats.
Cats eyes expand at night because They are bringing in more light to see into their eyes
yes
The cats eyes reflect the light.
well they eyes are like our eyes they can get blind
Because there's no light reflecting at the cat's eyes.
Yes, that is their purpose.
No. In the dark, the eyes of animals, especially animals that are nocturnal, will reflect light and look like they glow. This is the same thing that causes your eyes to "glow" red when someone takes a photo with a flash.
Both the cat's eyes and safety markers are capable of reflecting light .
because they have sharp eyes .
they reflect the light using the law of incidence
