Loretta is also rare, she is a het silver grey, and you can't find that size easily. Loretta is about 6 and a half inches from nose to tail and Sinclair is bigger, they also have cobby bodies and dish like faces. They are the result of selective breeding. But I discontinued Loretta's line because her mother carried a disease that seemed to pass to certain individuals in the litter, its not fatal or anything serious, but it's not good to continue the line if you know or suspect it may pass to the future generations and Loretta showed signs of it.
