I usually say that our girls are *very* fraternal, as I don't think they favor very much physically.
Personality-wise, the girls are pretty different, too.
But in response to the question, "Do they get along?" I always answer to the affirmative. They complement each other so amazingly well, each moving seamlessly around the other.
They're not always playing together, but it seems there's always some level of awareness as to where Sissy is and what she's doing.
And oftentimes, I'll find the girls like this...me not having said a word, but the two of them, almost perfectly mirrored to the other...
They may not share the same DNA, but this twinship deal is certainly a beautiful thing.
