Why are cat's pupils shaped the way they are?
111113
Cats are nocturnal hunters. They have frontally placed eyes that provide good binocular (depth-sensitive) vision. In addition, their eyes are much more sensitive than ours to low light intensities, and they are able to see with very little environmental light (their minimum light detection threshold is up to 7 times less than that of humans). Due to this sensitivity, they could be subject to eye damage during the day, and their vertical pupils could be an adaptation to avoid this. The pupil is the "window" through which light reaches the retina, and a vertical pupil that can contract to a mere slit, in combination with the eyelids that close perpendicularly to this slit, is able to keep excessive light out. In contrast, the cat pupil expands to almost circular shape in the dark. They have other adaptations for night vision (see link).\n\nOther crepuscular/nocturnal animals also have vertical pupils, e.g. many snakes and geckoes.

I'm not for sure but I think it is the way that it grows or maybe the fine little hairs that grow on them. This site might help you more than I could.

It's because it makes their fur stick to them and they hate the feeling of it. It has to do with the way the fur mats up. I am not sure why!

well first you can tell if they make up a name for you. second they constantly talk and flirt. also when you talk to someone that likes you their pupils get really big without them knowing. if they square up to you and talk that is another reason you know they do.

go on this website\n\nhttp://biology.kenyon.edu/heithausp/cat-tutorial/organs/welcome2.htm\n\nas it is all about cat anatomy,\n\nin simple terms though if you think of the anantomy of a human and turn it  180 degrees then you have a pretty good idea, the lungs are posterior the heart, i think i am ansewering the wrong queation, however this site would be a good source of information sorr i cant be more help good luck

Cats can see as well as humans,and at times better.Cat vision is designed for detecting motion,useful for hunting.Like humans,cats have binocular vision,although not as well tuned as in humans.This means a cat most likely sees in 3-D,as do humans,which is very useful for judging distance.And there are many other facts at this site http://videoforcats.com/catvision.htm

You pupils on average are about 7mm in diameter, but will close up (not completely!) in bright light to protect the retina, the part of the eye the 'receives' the image. The pupil wil also dilate (open up) to receive more light in low light sitiuations, so you can see more. This is called dark adaption, and can take several minutes to dilate to the maximum.

Each of the eyes are slightly recessed, and each eye points in a slightly different direction.  This makes it so that depending on which eye detects the most light, the insect is able to determine the direction of the light.  Humans, by contrast, find the location of light by having a lens which focuses the incoming light on the photo-sensitive retina at the back of the eye.

looks like your cat typed the question!

why do u look like a cat?

It is the negative image that is imprinted on your rod and cones inside of you eye. The image projected from your pupils.

Physics. Look at the shape of their skull and beak.

In the eye there r rods N cones. rods allow us to see details while cones colours! cats n dogs have more rods than human beings.

In an eye, there are photo-receptors made out of cells which are shape like cones and rods... \n\nWhen a cat, for example, is in a dark room, its pupils dilate wide and the minimal light in the room reflects inside the cat's retina where the photoreceptor's absorbs and creates this luminescence...

their pupils are pin dots and they scratch all over

i just checked and mine aren't dilated. however apparently they do dilate, but not just when aroused. it's whenever something interesting comes along.\n\nThe human pupil dilates if the person sees something (or someone) of interest or is aroused. Studies have shown that humans (especially females) are judged as more attractive if their pupils are wide open and more dilated than normal.
