Reply #14: I have two female cats

[dofus]

and I acquired the second one before anyone told me that two females can't get along. It took about a month, the first week or ten days with cat #2 isolated in a separate room. The next three weeks, cat #1 would hiss whenever she saw #2. Eventually that stopped (we've been a two-cat household for at least four years now) but cat #1 frequently dominates #2, who is the larger cat, BTW. It's almost always done in total silence, but #1 will suddenly, and as far as I can see for no reason whatsoever, jump on #2, swat her a good one, and then take off.

All that said, both cats are very sweet and loving. #2 sits on my lap whenever I get in a particular chair, and #1 often sleeps with me. Sometimes both spend the night on my bed in perfect harmony.

What might really be going on is that your physical accomodations are too small for the number of cats you now have. I've been told by several people who are very knowledgable about cats, that only a certain, somewhat flexible, number of cats can peacefully coexist in a given space. So if you can't move to larger quarters, you must find one of the cats a new home.

And good for you for rescuing the kitties in the first place.
