When Do Kittens Open Their Eyes and Ears?
Eyes start opening at about 8-12 days and are fully open by 2 weeks; ears open around the same timeFact
A kitten is born with eyes closed and ears folded. Cats Protection puts eye-opening anywhere from 5 to 14 days; the ASPCA says eyes begin opening at 8-12 days and are fully open by 2 weeks, when the ears are open too. Let each kitten open at its own pace.
Applies to: Newborn to about 3-week-old kittens, whether with a mother or being hand-raised.
Steps
The newborn baselineFact
- At birth the eyes are shut, the ears are folded down, and the kitten cannot stand
- Eyes open gradually over a few days rather than all at once
- One eye may open a little before the other, which is normal
- Newborn eyes look cloudy blue-grey and vision is poor at first
When the eyes actually openFact
- Cats Protection gives a window of 5 to 14 days old
- The ASPCA narrows first opening to about 8-12 days
- Eyes are usually fully open by roughly 2 weeks
- Don't try to pry eyes open or hurry the process
Ears follow a similar clockFact
- Ears are folded at birth and open around the two-week mark
- By about 3 weeks the ears start to point upright
- Hearing, like vision, is weak at first and sharpens over the following weeks
- Eye and ear opening together is a useful sign a kitten is near 2 weeks old
Normal vs keep-watching
Normal: Eyes opening any time between 5 and 14 days, sometimes one eye first, with a cloudy blue appearance and poor early vision.
Keep watching: Watch each day for both eyes fully open by around 2 weeks and ears beginning to lift by week 3.
When to contact a vet. If eyes are still fully sealed well past 2 weeks, or you see swelling, bulging, pus, crusting or discharge sealing the lids, contact a vet promptly, as neonatal eye infections need treatment before the eyes are even open.
What changes this answer
- Whether the kitten was premature or underweight
- Presence of eye discharge or infection
- Whether the exact birth date is known or estimated
Common mistakes
- Manually opening a kitten's eyes because they seem late
- Assuming blue eyes at 2 weeks are the permanent color
- Ignoring pus or crusting as just sleepy eyes
