I have a lot of cats and EVERY one of them is different how they react. Some are aggressive alphas, others the meek omega and then there are the peace loving deltas. I have one, long haired Heather, who is truly a delta. She gets along with everyone. Sometimes one alpha, Juliet, will hiss and challenge her to a fight, Heather just gives her a long look like "WHAT is your problem?" then gives her her back and slowly moves away from her. She even gets along with Gray, her mother and most alpha and aggressive, and Gray even licks her and rubs against her.
