Do Cats Prefer the Dark or Light? The Surprising Truth About Feline Vision


Cats are mysterious creatures. As pet owners, we often wonder about their behaviors and preferences. One question that frequently arises is whether cats prefer light or darkness. Do they like sleeping in a bright room or a pitch black one? Understanding a cat’s light preferences can provide insight into their natural inclinations and help owners create a comfortable home environment.

This article delves into the intriguing question – do cats like light or dark better? We’ll explore cats’ natural habits, research studies on feline light preferences, impacts of lighting, and recommendations for owners to satisfy their cat’s desires. Read on to uncover the truth about cats and light versus darkness.

Natural Habits

In their natural environment, cats tend to be crepuscular, meaning they are most active during the twilight hours of dawn and dusk (source). This is likely because their eyes evolved for low light hunting. Cats have excellent night vision thanks to a layer of extra reflective cells in their eyes called the tapetum lucidum. This allows them to make the most of low light conditions when hunting small prey like rodents, birds, and insects (source). Their eyes are optimized for detecting motion and detail in dark environments.

Indoor Lighting

When it comes to indoor lighting for cats, there are a few key considerations. Brighter light during the day can help entrain circadian rhythms so that cats are more active when people are typically awake ( Natural daylight or artificial sunlight lamps are ideal for providing a healthy day/night cycle. However, extremely bright light may cause stress for some cats.

Dimmer light is often preferable at night and in areas where cats retreat for naps or sleep. This allows them to hide away and sleep undisturbed ( Low level night lights or lamps in living spaces can provide enough light for cats to navigate comfortably without disrupting their sleep. Motion sensor lights in hallways or entries are another option to conserve energy while allowing cats to see at night when needed.

The key is providing a gradient of light – brighter in active living areas during the day, dimmer in restful spaces and at night. This caters to cats’ natural preferences while supporting healthy circadian rhythms in an indoor environment.

Light Preference Studies

Several studies have examined whether cats have an innate preference for light or dark environments. In one experiment published in the journal Applied Animal Behaviour Science, researchers tested light preference in 47 cats by recording the amount of time spent in lit vs. dark compartments of a test enclosure [1]. They found most cats showed a preference for the dark compartment, spending on average 76.5% of the time there. However, there was significant individual variation among the cats.

Another study published in the Journal of Feline Medicine and Surgery evaluated the lighting preferences of 17 cats while eating, resting, and playing using a choice test between bright and dim light [2]. The results showed cats preferred dim lighting when eating and resting. However, during play, they showed no significant preference between bright or dim light.

Overall, the research indicates domestic cats generally prefer dim or dark environments, likely an inherited tendency from being a crepuscular species most active at dawn and dusk. But lighting preferences can vary depending on the individual cat and behavioral context.

Breed Differences

Cats of different breeds exhibit tendencies toward light or dark, according to some studies. For example, a 2019 study published in found that certain breeds, like the Bengal cat, tend to be more active and aggressive than others like the Ragdoll, which tend to be more docile and inactive. The study suggests more active cats may prefer light so they can engage in more activity, while more inactive cats like darkness for sleeping.

Coat color and pattern also plays a role. Tabby cat breeds, recognizable by their striped coats, tend to be more active and playful. Studies show even among mixed breed cats, tabbies are more lively. Since they are more energetic, tabbies may lean toward light.

Conversely, black cats are known for being tranquil and aloof. Their dark coat may make them more inclined toward darkness. One theory suggests melanin, which controls coat color, also affects preferences for light or dark environments.

Kittens vs. Adult Cats

Kittens tend to prefer brighter environments compared to adult cats. As young developing cats, kittens are full of energy and curiosity. They want to explore their surroundings and play. Having adequate lighting enables them to see and interact with their environment more easily.

According to one source, kittens are often more sociable than adult cats, especially when they are under 12 weeks old. They desire companionship and affection from their humans and littermates. Kittens that are kept in brighter spaces are more likely to stay active and engaged during daytime hours when their owners are home.

As kittens grow older and transition into adulthood, their activity levels and sociability tend to decrease. Adult cats sleep more often during the day and become more independent. They may start to prefer dimmer environments that allow them to nap and relax undisturbed. However, each cat has unique preferences and personality traits.

In summary, kittens generally favor bright light conditions that stimulate their energetic and social nature. But adult cats may opt for darker spaces suited to their more laidback lifestyles. Cat owners should observe their pet’s habits and accommodate their individual lighting preferences.

Effects of Lighting

Lighting has significant impacts on cats’ behavior patterns and health. Cats are crepuscular, meaning they are most active at dawn and dusk. Their eyes are adapted to function optimally in low light conditions (Sunmory). Too much artificial light, especially blue light emitted from LED bulbs, can disrupt cats’ circadian rhythms. This can lead to sleep disturbances, anxiety, and other health issues (Energy5).

Cats need adequate lighting to perform essential behaviors like hunting, playing, and using the litter box. But excessive artificial light can overstimulate cats’ senses. It’s important to find the right balance of light and dark periods for your cat’s wellbeing. A combination of natural daylight and moderate artificial lighting tailored to your cat’s needs can support healthy behavior patterns.

Owner Recommendations

Most cat owners want to provide the ideal home environment for their feline companions. When it comes to lighting, there are a few tips owners can follow to accommodate their cat’s preferences:

  • Leave some lights on at night – Studies show that most cats prefer not to be in complete darkness, so leaving a night light on can help them feel more comfortable. Use dimmer bulbs or smart lighting to avoid glare.
  • Provide access to dark, enclosed spaces – Even if cats don’t want to be in total darkness, they still appreciate having access to covered beds, cat condos, and cardboard boxes to retreat to when they want shade or privacy.
  • Use natural lighting when possible – Open blinds and curtains during the day to let in natural sunlight, which helps regulate cats’ circadian rhythms and energy levels. You can also place cat trees near windows.
  • Avoid direct sunlight – While natural light is good, avoid placing food bowls, litter boxes, and beds in direct sun which can cause overheating. Provide shaded areas cats can relax in.
  • Consider breed and age – Siamese and Burmese cats tend to be more sensitive to light. Kittens and older cats may also need more moderate lighting. Observe your cat’s preferences.
  • Use smart devices – Smart bulbs, motion sensors, and light timers allow you to program customized lighting schedules to match your cat’s needs and behavior patterns.

With some adjustments to home lighting and providing access to both lit and shaded areas, owners can help their cats feel relaxed and comfortable day and night.


Cats are crepuscular creatures, meaning they are most active at dawn and dusk when natural light levels are lower. While some cats do prefer brighter light, most cats seem to like moderate lighting that mimics their natural habitat. Studies have shown that cats feel safer and more secure with lower light levels, likely because their excellent night vision gives them an advantage in dim environments.

Based on the research, the ideal home lighting for your cat seems to be a soft, moderate level that allows them to see well but doesn’t overwhelm their sensitive eyes. Consider using diffused light sources, placing cat towers or beds in shaded spots, and providing hiding spots if your home has very bright lighting. Observe your individual cat’s preferences and make adjustments so they have access to their optimal light level at different times of day. With a little care and observation, you can create a home environment tailored to your cat’s unique needs and preferences.
