When do cats open their eyes? All you need to know

The development of newborn kittens is a fascinating process, full of important milestones that mark their growth and adaptation to the world around them. One of these milestones is when kittens open their eyes for the first time. Below, we explore this exciting time and answer common questions about kitten eye development.

Early kitten development

Kittens are born with their eyes completely closed and cannot see. This is because their eyes are still developing and need more time to mature properly. During the first weeks of life, kittens are completely dependent on their mother for food, warmth, and protection.

When do kittens open their eyes?

Kittens usually begin to open their eyes between 7 and 10 days of age. However, this process can vary slightly between individuals, with some kittens opening their eyes a little before or after this time range. It is important to remember that at first your eyes will be partially open and you will not see clearly. Kittens' vision will continue to develop and improve in the coming weeks.

Eye opening process

The process of opening kittens' eyes is gradual:

  1. Day 1 to 7: Eyes remain closed.
  2. Day 7 to 10: Eyes begin to open slightly.
  3. Day 10 to 14: The eyes continue to open more and the kittens begin to see shapes and lights.
  4. Week 3 to 4: Kittens' vision improves significantly, although it is not yet completely clear.


Kitten Eye Colors

When they open their eyes, all kittens have grayish-blue eyes. This color will change as they age, usually around 6 to 7 weeks of age. The final color of a cat's eyes is not established until they are between 3 and 4 months old.

Care during eye development

It is essential to allow kittens to open their eyes at their own pace and avoid forcing the process. Handling a kitten's eyelids can cause damage or infection. Here are some tips for caring for kittens during this period:

  • Clean environment: Keep the nesting area clean and free of dust.
  • Good nutrition: Make sure the mother is well fed and healthy so she can properly care for her young.
  • Observation: Monitor kittens for signs of eye infection, such as redness, discharge, or swelling. If you notice anything unusual, consult a veterinarian.


Eye infections in kittens

Sometimes kittens can develop eye infections that need veterinary attention. Signs of infection include:

  • Redness: Red or swollen eyes.
  • Discharge: Presence of pus or thick fluid around the eyes.
  • Swelling: Eyelids that are swollen or closed abnormally.


If you notice any of these symptoms, it is crucial to take the kitten to the vet as soon as possible for proper treatment.

The moment kittens open their eyes is an exciting milestone in their development. Generally, this occurs between 7 and 10 days of age, although it can vary. Providing a clean, safe environment and watching for any signs of eye infection is essential to ensure healthy development. Always consult a veterinarian if you have concerns about your kittens' health.
