It is not easy to pair up or get your chin a companion if your chin is more than a years old...
As they already developed their own character and used to living alone...
Tried to get mine a companion, failed everytime, so didnt get any in the end...
ping, i suggest you read more about them... although they are less maintance rodents they still like someone to play with and they are not easy to tame... Mine never got used to me carrying her...
Dun get them on impulse like they are cute den get bored of them and sell away or neglect them...
