Why are some cats’ pupils round and other’s have slits?

Answer 1

All cat eyes are have "slits" and when you see a cat's pupils become round, it's a natural dialation. Just like your eyes, they respond to light and darkness by getting larger or smaller.

Answer 2

Actually ALL cats' pupils are vertical slits that dilate depending on the amount of light. When it is day time and bright in the room, the cat's pupils will look like a black vertical strip. When it is dark, the slits dilate to take in as much light as possible. Fully dilated, the pupils appear big and round - just like our own pupils when we are in a darkened room.

Answer 3

All cats' pupils are slits. The way they dialate differs from humans because they expand width-wise instead of all around. Sometimes it does seem like a cat's pupils are allways round and just don't go back to being a slit; if it seems like this, the cat is probably accustomed to more light then there is when you see the cat.

Answer 4

Hi,

All domestic cat's pupils can change from round to elliptical (slits). The pupil is round when it is dilated and letting in a lot of light, or the pupil can shrink in from the sides until it is elliptical. When elliptical, a cat's eyes look like a slit, stretching from top to bottom. This special adaptation allows a cat to partially close its eyelids (squint), covering only part of the pupil but not all of it. This gives the cat a certain amount of manual control over the amount of light let in. If the pupil was simply reduced to a small circle, squinting the eyelids would cover the pupil all together.

When opening (or dilating), a cat's pupils can dilate much faster than yours or mine. They can also dilate three times larger than yours or mine can. This lets in a lot of light, and is one of the reasons cats have their famous ability so see well in low light. They don't see well in total darkness, which is a popular myth, but it is true that their eyes' ability to dilate to such a large degree is part of the reason they have an exceptional ability to see in poorly lit conditions.

Answer 5

All cats pupils can be either round or slits--depending on the lighting conditions.

Just like humans, the cat's publil cand expand to let in more light when its dark or contract to keep out excess light when its bright. However, in humans, the pubil remains circular--but the diameter increases or decreases. A cat's ey is structured differently--when its in bright light, it becomes a narrow slit instead of a tiny point like a human eye.

Answer 6

Cats' pupils become large and round in the dark. In the light, they become small slits.

Answer 7

all cats eyes have the same pupil if their is light in their eyes they are slits but when they are in the dark they are round weird but true

Answer 8

It's because the light.Cats have big round pupils in the dark to catch light and slits to catch a little when it's bright.My kitties always do that because they live outside on my farm.It' sorta cute.

Answer 9

its depends on the lighting my cats eyes go from slit to rounded all the time it just the lighting

its not species

Answer 10

The scholars are huge and round lots of the time, jointly with even as the cat is interior at evening lower than widespread gentle situations. the in trouble-free words time they grow to be slits is even as the cat is outdoors in astounding solar.
