British Shorthair kitten's eye color typically starts to change around 4-5 weeks of age. The full development and stabilization of their eye color can take up to 6 months.
At what age do British shorthair kittens' eye color change? - in detail
The eye color of British Shorthair kittens can change significantly during their first year of life, with notable shifts occurring at specific ages. At birth, most British Shorthair kittens have blue eyes due to the absence of melanin in their irises. This initial blue phase is universal and not indicative of their future eye color.
Within the first few weeks after birth, usually between 4 to 6 weeks, the kitten's eye color may start to change. During this period, the eyes might darken from blue to a deeper shade such as green or hazel. This transition is influenced by the amount of melanin produced in the iris, which is determined by genetics.
By the time British Shorthair kittens are around 3 to 4 months old, their eye color typically stabilizes and becomes permanent. At this stage, the eyes have fully developed their final pigmentation, and any further changes are rare. The most common adult eye colors for British Shorthairs are green, gold, or copper, though blue eyes can persist in some cases, especially if the kitten carries a specific gene variant associated with blue eyes.
It is essential to note that the exact age at which a British Shorthair kitten's eye color changes can vary depending on individual genetics and developmental factors. While 3 to 4 months is a common benchmark, some kittens may exhibit changes earlier or later within the first year of life.
In summary, the eye color of British Shorthair kittens undergoes significant changes during their early development, with initial shifts often occurring between 4 to 6 weeks and final stabilization by 3 to 4 months of age. Genetic factors play a crucial role in determining the ultimate eye color of these felines.
