My Kimba had feral ways and while he loved to be petted, he would bite, too. He got in severe cat fighths with both of the other boys. It was touch and go for awhile, but now the fights are down to the occasional growl and right now, he and Ming (mortal enemies or so I thought) are both sleeping peacefully on my son's bed.
They're not right next to each other, but they are within 2 feet of each other and no growls! Give it time, it will happen; On April 5th, Kimba will have been with us one year. It took a lot of patience sometimes, and I have scars on my left leg from where I stupidly stepped in between him and Ming during an early altercation (did I mention he used to bite?) but it was more than worth it. He is such a sweetie now, a true lovebug, lap kitty!
