Various Influencing Factors

Laboratory experiments (!) have demonstrated that several factors influence the timing. These include paternity, the kitten’s sex, the age of the mother and exposure to light.

For example, kittens reared in the dark opened their eyes earlier. Kittens of younger mothers and female kittens also opened their eyes earlier.

Paternity is the most important factor. By this it is meant that inherited genes strongly influence the timing of eye-opening by kittens.

Vision begins to play a more important role in their lives when they are about three weeks of age.

Improvements

Their eyesight improves gradually until the fluids in the eye clear at about five weeks. Visual acuity improves on an ongoing basis until the kitten is three or four months old.
