This proud farmhouse Momma and her sweet blue eyed kittens.
All kittens have blue eyes due to a lack of Melanin, as young kittens don't produce very much. But as they grow and age, the kitten's body produces more, triggering the eye color change, which occurs at around 4 weeks of age and progresses until about 10 weeks of age.
