These are two male fancy rats that grew up together since they were born. The silver one is named Kiryu and the black one is Shadow. Kiryu is friendly and curious, and Shadow is very shy. I do not know much about their breeds. They are gifted to me as 'fancy rats' .I will be moving to another state very far away and would not be able to take them with me. Need a new home asap! Will come with a cage and supplies. I've had them for 9 months.
