A hamster with one black eye and one red eye may have a genetic condition known as heterochromia, where the two eyes have different colors. This can occur due to variations in pigmentation and is generally harmless. However, if the change in eye color is sudden or accompanied by other symptoms like swelling or discharge, it could indicate a health issue, and it's best to consult a veterinarian.
