A full reading for Rat × Virgo meeting Rat × Pisces 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.
Both the blessing and the bane of members of this introverted DoubleSign is the capacity for complete disregard of all forms of outside impetus. Rat/Virgos have a private clock that tells you your own sweet time in which to do things, and you stick to it, regardless of the demanding voice, the wheedling phone call, or the looming deadline. Such independence can naturally lead to an unhealthy isolation in matters of the heart, and you should remember to make an effort now and then to ditch your Virgo half, have a night on the town and rub some elbows with the fast crowd once in a while.
The Rat/Pisces is half of the whole picture. As a member of this sign, you prefer to function as one of a two-person team. In the best case scenario the other person is the permanent love interest (marriage is very much in favor with you nesting homebodies). In every other case the second person will be found outside of the love relationship -- perhaps taking the identity of a co-worker, mentor, or friend.
