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.
