Introduction: Beyond the Sunbeam — Why Cats Choose Where They Rest
It's a familiar sight: your cat basking in a sunbeam one moment and hiding in a dark wardrobe the next. But have you ever stopped to wonder, do cats prefer light or dark spaces? Or why this behavior changes so frequently?
At PetCareShed, where feline wellness is our priority, we dug deep into the science, history, and psychology of cats to unveil the true secrets of feline comfort. This isn’t just a matter of where your cat naps — it’s about how to create a home environment that aligns with their instinctual behaviors, promotes relaxation, and reduces stress.
The Science of Light and Dark: Understanding Cat Vision and Preferences
How Cats See the World
Cats are crepuscular — most active during dawn and dusk. This ties closely to how their eyes work:
- Tapetum lucidum: A reflective layer behind the retina that improves night vision.
- Rod-heavy retinas: Cats have more rod cells (light-sensitive cells) than cone cells (color-detecting ones), giving them excellent low-light vision.
- Color perception: Cats mostly see in muted blues and greens, meaning bright or artificial lighting isn’t visually stimulating.
Implication: Cats don't need bright light to feel safe or see clearly. They rely more on shadow contrast and subtle light gradients.
“Cats evolved to hunt in twilight conditions, which is why dim lighting feels more natural to them.” — Dr. Susan Hazel, Animal Behaviourist, University of Adelaide
Evolutionary Preferences: From the Wild to Your Couch
Wild ancestors like the African wildcat sought shelter in burrows, bushes, and caves — dark, concealed places where they could rest without fear of predators. Domestic cats have retained this instinct, which is why you’ll often find them snoozing in:
- Closets
- Under beds
- Cardboard boxes
- Behind furniture
At the same time, sunbathing fulfills another need: warmth. Cats have a higher thermoneutral zone than humans (about 30–38°C), so basking helps regulate body temperature.
Mood Lighting: The Role of Light in Feline Emotional Health
How Light Affects Stress and Behavior
Studies show that cats exposed to continuous bright artificial lighting can experience elevated cortisol (stress hormone) levels. On the flip side, environments that offer:
- Dim corners
- Shade options
- Gradual light transitions
…allow cats to self-regulate their exposure, reducing overstimulation and anxiety.
A 2019 study published in Applied Animal Behaviour Science revealed that cats housed in environments with both natural light and dark hiding spots exhibited:
- Lower stress signals (e.g., less tail flicking, fewer dilated pupils)
- Improved sociability
- More predictable sleep cycles
Creating the Ideal Environment at Home
Best Practices for Lighting in Cat-Friendly Homes
You don’t need to choose between a fully lit room or a pitch-dark one. The key is balance and choice.
Here’s how to build a lighting environment cats actually love:
✅ Provide Mixed Zones:
- Sunlit spots near windows or cat perches
- Shaded nooks like covered beds, cabinets, or tunnel toys
✅ Use Natural Light When Possible:
- Open curtains during the day
- Avoid intense overhead lights during evenings
✅ Mimic Natural Light Rhythms:
- Use smart bulbs with sunrise/sunset simulation
- Turn off bright lighting at night to support rest
✅ Add Enclosed Spaces:
- Covered beds or domes let cats choose darkness when needed
- Furniture with hiding holes, like cat trees, supports their instinct to shelter
Tip: Our Covered Cat Beds Collection is designed to replicate the comfort of hidden, dark spaces while keeping your pet cozy and stylish.
When Cats Seek the Dark: Understanding Hiding Behaviors
Not all retreats into darkness are about comfort. Sometimes, they’re a sign of:
- Stress
- Illness
- Fear or trauma
- Sensory overload
If your cat is suddenly hiding more than usual, consult your vet. Chronic hiding can be a red flag.
“A sudden shift in lighting preference — like choosing dark places and avoiding daylight — might indicate a health or behavioral concern.”
— Dr. Sarah Ellis, International Cat Care Behaviour Specialist
Why Cats Also Love Sunlight (But Not Always Too Much)
Despite loving the dark, cats adore lounging in the sun. Why?
Sunlight Offers:
- Warmth and comfort
- Relief for aging joints
- Scent enrichment (sun-warmed surfaces release more aroma)
- Vitamin D absorption (indirectly, via grooming)
But too much sunlight can lead to:
- Overheating
- Sunburn (especially in white cats)
- Disrupted circadian rhythms
Important: If your home gets intense direct sunlight, consider adding sheer curtains or shaded perches to help your cat manage exposure.
The Influence of Age, Breed, and Personality
Kittens tend to explore more and prefer lighted spaces out of curiosity.
Adult Cats appreciate the choice between bright and dark — often rotating between both based on activity level.
Seniors might seek out warmth more often and nap in sunbeams for longer periods.
Breed also plays a role:
- Oriental breeds like Siamese may enjoy interaction and prefer well-lit, social spaces.
- Shyer breeds like British Shorthairs often seek dark, enclosed areas for rest.
Should You Leave Lights On for Your Cat at Night?
Leaving lights on isn’t necessary. Cats see well in the dark. However, for kittens or senior cats with diminished night vision:
- A soft nightlight near the litter tray or food station can be helpful.
- Avoid full-spectrum lighting or overly bright LED bulbs during the night.

Common Myths Debunked
❌ “Cats are nocturnal — they hate light.”
→ Cats are crepuscular, not nocturnal. They enjoy both light and dark but in moderation.
❌ “Cats can’t see in total darkness.”
→ True. They need minimal ambient light — they can’t see in absolute darkness, just like humans.
❌ “Hiding in the dark means the cat is scared.”
→ Not always. It can also mean your cat feels safe and calm.
Conclusion: Let Your Cat Choose Their Light
Ultimately, comfort comes from choice. Your cat isn’t strictly a fan of light or dark — they appreciate the ability to move between both. As a responsible pet owner, your job is to create an environment that mirrors their natural rhythms and instincts.
Providing both sunny nap zones and cozy, shaded hideaways ensures your feline friend feels safe, in control, and at peace.
And remember — the best cat spaces are ones where they decide what comfort means.

Is sunlight harmful to cats?
Moderate sunlight is beneficial, but too much can overheat them. Always provide shaded alternatives.
How can I tell if my cat prefers light or dark spaces?
