What eye colors can a Chartreux have?
The accepted eye color of Chartreux cats, according to breed standards, ranges from gold to copper. Their eyes are one of their most striking features, providing a vivid contrast to their blue-gray coat. The eyes should be deep and rich in tone, whether they are bright gold or a warm copper, contributing to the cat’s expressive and engaging appearance. Occasionally, some Chartreux cats may have eyes that appear more greenish rather than the accepted gold or copper tones. This is less common but can still be found.
