I wish she hadn't, but Kitty brought a mouse into the house at 5:15AM, but promptly
lost it behind a large immovable bed.
Usually I end up flushing out the mouse for her, and Kitty always takes credit, but
that's o.k.
The amazing thing is that she is able to catch mice in the dark,
but since cats only require only one-sixth of the light needed for human vision, she
has a definite advantage.
Kitty's elliptical slit-like pupil enables it to open wider than a round human
pupil, but there are other factors; such as having a proportionally larger eye.
Her cornea is more curved, which allows greater edge sharpness.
The anterior chamber is larger, which allows more light to reach the retina,
but she also has the Tapetum Lucidum, which acts as a mirror behind the retina
to reflect light back at light sensor cells.
Cats also have a greater percentage of Rods to help with night-time vision,
and they have a greater concentration of receptor cells
along a broad horizontal band in the center of the eye which help discern sideways movement.
Take a look at Kitty's eye.
