I've had Streak and Trinity for about nine months now, and Male still growls and hisses at them, or slaps them when they invade her "space".

Female is a lot more accepting.

I had to bring them together slowly -- I kept Streak and Trin in the den the first two months, and would allow them frequent glimpses at each other.

Next I put their food bowls side by side, and let them eat together. I kept this up for about a month, but would always put Trin and Streak back in the den after they ate.

At about four months, I let it all hang out.

My house has never been the same. ;-)

Patience, Grasshopper -- It will work out. They will come to accept each other, if only grudgingly.

Abby is top cat, and he's not going to give up his territory without some problems.

You also might want to get some Feliway (cat pheremones). Since felines operate mostly by scent, Feliway will help bridge that "getting to know you sniffing".
