🐱 Vet Guide: When Do Kittens Open Their Eyes? 2025 Edition 🍼
By Dr. Duncan Houston, BVSc — veterinarian & Ask A Vet founder 🐾
1. 👶 Understanding Kitten Birth Development
Newborn kittens are born blind, deaf, and unable to regulate body temperature :contentReference[oaicite:2]{index=2}. Their eyes and ear canals are fully closed, and they rely entirely on their mother for heat, nutrition, and hygiene.
2. ⏳ When Do Eyes Begin to Open?
Eye-opening typically begins at 7–14 days old, though some kittens may start between 2–16 days :contentReference[oaicite:3]{index=3}. The lids gradually separate, and kittens may squint or open one eye before the other.
3. 👁️ Vision Development by 3 Weeks
By around 3 weeks of age, kittens typically begin to focus with both eyes and explore their surroundings. Vision improves gradually over the next few weeks :contentReference[oaicite:4]{index=4}.
4. 🎨 When Does Eye Color Change?
Kittens are born with blue eyes due to immature pigment cells. Their permanent eye color usually appears between 7–8 weeks as melanin production increases :contentReference[oaicite:5]{index=5}.
5. 🛡️ Why Eyes Stay Closed Initially
- Protects developing tissues from infection and injury :contentReference[oaicite:6]{index=6}.
- Helps maintain moisture before tear glands mature.
- Avoids bright light while neurological and ocular systems mature.
6. 🧼 Caring for Opening Eyes
- Avoid bright lights; keep the nest dim and calm :contentReference[oaicite:7]{index=7}.
- Gently clean discharge with a warm, damp cloth; no soap :contentReference[oaicite:8]{index=8}.
- Never force eyelids open—they will open naturally when ready.
7. ⚠️ Red Flags to Watch For
- No eye opening by 16–21 days.
- Persistent discharge, redness, or crusting.
- Swollen eyelids or signs of infection.

10. 💡 Final Thoughts from Ask A Vet
Watching a kitten open its eyes is magical! Most do so between 7–14 days (range 2–16). Their vision sharpens by 3 weeks, and true eye color emerges by 7–8 weeks. Keep their world soft, warm, and safe—and monitor for any issues.
