Photography Challenge Day #21

DSCN3091 A fun fact about the cat’s eyes:
Those vertical pupils aren’t just for decoration.
Cats and other animals that are active in the day and night have pupils shaped like vertical slits because that shape allows the pupil to change size much faster than the round pupils we humans have. The smaller the pupil, the less light comes in, so cats are much less likely to get blinded by sudden changes in light levels than we are.
Isn’t God so amazing??
