A full reading for Snake × Sagittarius meeting Rat × Cancer is on the way. In the meantime, the score above is computed from the canonical element matrix and sign-cycle distance, and the profiles below cover each side individually.
The Snake side of your DoubleSign looks before the Sagittarius side leaps -- a very prudent combination. The Snake/Sagittarius has a perceptiveness that is uncanny, and you are very much a "people person" in that you can read everyone around you like a see-through comic book. Because of this enjoyable skill, you may wish to consider a career in psychotherapy.
The product of two intensely cerebral signs, a Rat/Cancer's personality is a private one. Nothing is more attractive for you than to curl up in a safe haven and navel-gaze for prolonged periods. Intellectual and emotional, you are a superb creator and make an ideal storyteller, whether professional or otherwise, thanks to your Cancer inheritance. In love you can be a mixed blessing.
