Most cats are not inherently scared of the dark, but some individual cats and kittens can feel anxious in complete darkness, especially if they’ve had bad experiences or have vision or health problems. Leaving a small night light on often helps nervous or very young/old cats feel safer and move around more confidently.
How cats see in the dark
Cats have eyes adapted for low light, with large pupils, many rod cells, and a reflective layer that lets them see far better than humans in dim conditions. They still cannot see in absolute pitch black, so a tiny bit of ambient light makes a big difference for them.
When a cat may fear darkness
Fear usually comes from what happens in the dark, not the dark itself.
- Past negative events (fights with other animals, loud noises, moves to a new home) can make a cat associate darkness with danger.
- Kittens and older cats may get disoriented or anxious in very dark spaces, especially if their vision is changing.
Signs your cat is scared
Common signs include crying or yowling when lights go off, pacing, hiding, dilated pupils, sweaty paws, and a fast heartbeat. Bumping into furniture or suddenly refusing to move around in the dark can also suggest vision issues that need a vet check.
How to help a worried cat
- Leave a dim night light near key areas like food, water, bed, and litter box.
- Keep the night environment predictable: same layout, minimal sudden noises, and safe hiding spots.
- If your cat suddenly seems afraid of the dark or disoriented, ask a veterinarian to check for eye disease or other medical causes.
