how are cats eyes different than human eyes?

Cat pupils close from the sides to centre in a vertical line... \nHuman pupils stretch and opens in a circle...

Cats are independent and appear to be less loyal as they are not "pack" animals like dogs. Dogs think you are part of their pack (think wolves) and except for my dog they think you're the leader of the pack, hence their loyalty.  Cats are not pack animals and typically rely on their own wits for survival (think lion) but treated well will always love you as much as your dog

Eye color is the pigmentation and reflections of particles in your eye. Basically the lighter the eye the less pigmentation is in that eye.  BLue eyes have less pigmentation than brown eyes. The way that the color is reflected gives the different apperance of the eye color. \nMy eyes are green. They arecool.

Mammals such as your cat and us evolved from early amniotes called Therapsids, as the Professor stated. Therapsids were sometimes called "Mammal-like reptiles" but in fact, all the "modern reptiles" (lizards, snakes, crocs, turtles) evolved from another "branch" of early amniotes. The things that all amniotes have in common either 1) were inherited from a common ancestor or 2) evolved independently and achieved similar aspect. Most of the times you can tell when this is the case because such features look superficially similar, but not so much under closer examination. For example, vertical pupils are characteristic of many nocturnal animals that are very dissimilar, such as cats, alligators, or some frogs; these were acquired independently and these animals regulate their eyes somewhat differently. However, all vertebrates have one pair of eyes; this is an inherited shared trait.

Superior huh? First of all cats don't have a "language" per se. Everything is based on body language and tones. Humans can also do this. Humans can communicate just like cats (albeit on the most fundamental level) with any other human in the world. Don't believe me? Go to any person who doesn't speak your language. Watch their body language. I guarantee you will be able to understand exactly when they feel scared, happy, surprised, mellow, nervous, etc. And if you just listen to the tone of their voice as they speak to someone else, you will be able to tell when they sound angry, happy, depressed, etc. See, cats and humans can communicate on the same level. Though we can't carry on conversations, neither can cats, we can understand some basics. For example if two cats meet up from differnt parts of the world, they will only be able to understand the most basic things from each other, just like they would understand from their own kind in their own country. Example of things they could tell; I'm in the mood for sex, This is my territory get out, I'm hurt, I'm happy. All of these things can also be communicated by humans to any other human.\n\nhope this helps.

Cat have a memory that is 200 times more retentative then a dogs.  The feline uses his/hers memory for what he regards as usful functions.  So a cats memory is quite selective.

No.\n\nFish can see in five colours. We can only see in three (although some women can see in four). Humans have a blind spot caused by the wiring of their retinas; octopuses do not. The resolution of human vision is not as good as that of hawks. A hawk's vision is about 20/5; they can see an object from about four times the distance of a human with 20/20 vision.\n\nAnd that's just the eyes.\n\nOur skin is not as thick and tough as a rhinoceros', so provides us no protection. It has no fur to keep us warm. We are not the fastest organisms. We are not the only organisms that know how to use tools (see Caledonian crows, some apes and beavers).\n\nAs far as evolution is concerned, if it survives, it's superior. If it doesn't survive, it's inferior. By that standard, all animals are superior, and by inference, all plants.

This is a genetic matter\nIt depends to you mother and father's eye chromosomes\nAt first humans they used to have brown eyes.\nWith mutations in chromosomes, colors like \nblue, green, black, hazel were developed.

Do your eyes get red and itchy. Since peopl are not alergic to the actual cats pursay, and they are allergic to the cat hair when you get cat hair in your eye/ near you eyes then they will get red and itchy. Sometimes you can still be allergic without getting this common symtom so there are tests you can do in the doctors office.

Absolutely....they communicate with each other, as well as humans.  Maybe we can't tell exactly what they're saying, but they're trying.  My cats talk to me all the time, and just like a baby has different cries....my cats have different meows!

The domestic cat is a member of the genus Felis.  Lions and tigers are members of the genus Panthera.  The house cat is as closely related to the lion as it is to the tiger.  \n\nThis rotten forum won't let me draw a picture, so here's the best way I can explain it in text.\n\nImagine you're an only child, but your uncle (father's brother) has two children.  Which of your uncle's children are you more closely related to?  The answer is neither, you are equally related to both of them.\n\nIt's the same here.  Panthera and Felis share a common ancestor many millions of years ago, while lions and tigers only separated a short time ago.

- cats are better because they don't need to get walked several times a day (they never need to get walked!)\n- they smell much better\n- they are cleaner (they wont eat other animals poo)\n- they are way more inteligent\n- their fur is much softer\n- you can leave them for the weekend with out any problems\n- they are smaller\n- they dont chew up your shoes (I really love my shoes)\n- they will get rid of your mouse problem, guarenteed.

Brown-pigmented eyes are so dark that there could easily be green-eyes pigment there-and a previous answerer went into detail about the relative level of pigment, so there is no fear of infidelity.\nBut, in the case of kitty....\nNot to put too fine a point on it, but Im not aware of any genetic way two blue-eyed people can have a brown-eyed child normally... Blue eyes are recessive, being a very low level of pigment-If either parent carried a different gene, one that coded for brown eyes, then *they* would be brown eyed.  If you have brown eyes, but both your parents have blue eyes, I would suspect that one or both were not your biological parent.

dog, cats, and some other animals have what is called a tapedum lucidum, it is a part of the eye that reflects all available light...this is why animals can see better in the dark than humans, as we don't have one.\n\nsorry redtail...the tympanic membrane is in the ear...you must have meant tapedum lucidum, right?

Brown eyes\n \nBrown eyesThe vast majority of the world's people have dark eyes, ranging from brown to nearly black. Light brown eyes are also present in many people, but to a lesser extent. Most of the original inhabitants of Africa, Asia, and the Americas have brown eyes. Brown eyes are also found in Europe, Oceania and North America, though within European populations they are not predominant to the same extent

There's a peak absorbance of rods and cones in the retina.  Humans have three peaks which represent the primary colors (for light) red, green, and blue.  The colors we see are our brain's interpretation of input on those three colors plus general light level input from rods.  Based on the numbers of rods and cones and the absorbance spectra of the different cones, researches can get an idea of the color vision of different animals.\n\nMost mammals are dichromatic (two colors).  Note how non-colorful they tend to be.  Certain primates are trichromatic (three colors).  Birds, reptiles, amphibians, and insects are also trichromatic or more.  Note how colorful they tend to be.

Its something to do with the eyes I think. Sorry I cant give any further info.
