Hi!
> (actually, two females are more likely to fight)
I'm taking this out of context and probably you mean that it's difficult
(but not entirely impossible) to introduce 2 adult females which is
probably true (I never tried).
However I never had any problems with two females who grew up together.
They were always peaceful for all their lives. It's with 3 or more that
you are in for some trouble. So if they are about the same age I think
it's quite unlikely that problems will arise. At least not more likely
than with two males. Or did anybody make other experiences?
