Cats are crepuscular, meaning they have better night vision than humans. They rely on their senses of smell and hearing, as well as their whiskers, to navigate in the dark. While it's not necessary to leave a light on for cats, kittens may benefit from a night light to help them get accustomed to a new environment.

What You'll Learn
Kittens don't need lights on to see in the dark
However, it's important to note that while cats don't need lights on to see in the dark, they also don't have superhero-like night vision. They can't see in total darkness, but they can see their way around in low levels of light. This is why they are mostly awake and active during twilight periods such as dusk and dawn.
When it comes to sleeping arrangements for kittens, it's generally recommended to keep the lights off. Leaving a light on could disrupt their natural body clock and stimulate their senses, leading to more activity instead of sleep. In addition, bright lights can affect a cat's internal circadian rhythm, interfering with their natural routine.
For new kittens, it may be helpful to leave a low night light on for the first few nights until they get accustomed to their new environment. This can make it easier for them to navigate their surroundings and find their litter box, food, and water bowls. However, once they are settled in, it's best to turn off the lights to help them develop a healthy sleeping routine.

Cats' whiskers help them navigate in the dark
Cats have excellent night vision, but their whiskers also play a crucial role in helping them navigate in the dark. Whiskers are "stiffer hairs" with many nerve endings embedded around the hair follicle, making them "sensory organs". They are also known as vibrissae or tactile hairs.
Cats have whiskers on their muzzle, above their eyes, in their ears, and on their front legs. These whiskers are symmetrical, which helps cats measure their surroundings accurately. The whiskers near the cat's nose and mouth are especially helpful when it comes to detecting objects and prey. For example, when cats open their mouths to catch prey, their whiskers tell them where their prey is, as their vision becomes partially blocked.
Whiskers are also useful for cats when they are playing with objects, grooming, feeling where other cats are, and interacting with them. They can help cats figure out if they want to pick something up or if they can fit through a small space.
The whiskers on a cat's front paws make up for their short-sightedness. If they have caught prey, the whiskers give them an idea of where it is in relation to their feet.
Overall, a cat's whiskers, along with their night vision, sense of smell, and sensitive hearing, enable them to navigate and hunt effectively in low-light conditions.

A night light can help a kitten get accustomed to a new environment
A kitten's first night in a new home can be challenging. They have to adjust to new people, sights, and smells, and they may feel scared without their mother and littermates.
Kittens like to feel sheltered and secure, and they can see in very low light. So, while it's not necessary to leave a light on for them, having a low night light on for the first few nights in a new environment can help them get accustomed to their new surroundings. This is especially true if you live in an area that tends to be very dark.
Kittens will seek out warmth and cosiness when they want to sleep, so it's best to provide them with a secure spot, sheltered from drafts and warm enough for them to settle in. You can also add soft blankets to make them feel more comfortable.
Remember to keep their litter tray, water, and food bowls close by, but not next to each other. Additionally, removing electrical cords and breakable items from their reach will help keep them safe and give you peace of mind.
By providing a comfortable and secure environment, you'll be helping your new kitten adjust to their new home and get a good night's sleep.

Cats' other senses help them get around in the dark
Cats have several other senses that help them navigate in the dark. While they are not truly nocturnal and do need some light to see, their other senses are more specialized and precise, allowing them to live easily in low-light conditions.
Firstly, cats have a superior sense of smell. Their olfactory epithelium is five to ten times larger than a human's, giving them up to 200 million odor-sensitive cells, compared to our mere 10 million. This means they can detect even the faintest of scents. They also have the Jacobson's organ, which is a scent organ in the roof of their mouths. When a cat wrinkles its muzzle and lets its tongue hang, it is opening the passage to the vomeronasal, which is called gaping.
Secondly, their hearing is also much more acute than humans'. Cats can hear much higher-pitched sounds, up to 64 kHz, which is 1.6 octaves above the human range. Their ears can swivel and pinpoint the location of a sound within inches in less than a second, helping them to locate prey.
Thirdly, their whiskers, or vibrissae, are highly sensitive and help them to detect subtle air movements that indicate the presence of prey and enable them to navigate around obstacles. The upper two rows of whiskers can move independently from the lower two rows, providing greater precision.
Finally, while cats do not have true night vision, their eyes are adapted for superior vision in low-light conditions. Their pupils expand up to 300 times when it is dark, allowing more light into the eye. Their eyes also contain a reflective layer of tissue called the tapetum lucidum, which reflects light back to the rod cells, enabling them to absorb more light. This is what causes the eyes of cats to glow when light shines on them in the dark.

Cats' eyes are excellent at reflecting light
Cats' eyes are highly reflective, and this is all down to a layer at the back of their eyes called the tapetum lucidum. This layer reflects light back to the retina, giving the photoreceptor cells a second chance to absorb the light. This is why cats have such good night vision.
The tapetum lucidum is like a mirror, and it's what causes eyeshine. Some light bounces off the tapetum lucidum and exits the eye, creating the glowing effect. The colour of the eyeshine depends on the pigments in the tapetum lucidum, which is usually made from a mixture of riboflavin and zinc molecules. Most cats' eyes glow green, but the spectrum includes blues and yellows.
Cats are crepuscular, meaning they are most active at dawn and dusk when light conditions are poor. They are skilled hunters, and their prey are often small, nocturnal animals. Their night vision is much better than ours, and they can detect light levels six times lower than humans can.
Cats have large pupils and corneas, which allow more light to enter the eye and hit the photoreceptor cells. They also have a higher concentration of rod cells, which are primarily concerned with lower light and peripheral vision.
Cats' eyes don't need to be in total darkness to function well. They can still navigate in the daytime, although their tapetum lucidum is not as helpful in bright light. Their peripheral vision and motion tracking are good, but their visual acuity is poor, and they can probably only see about 20 feet away.
