With mine, Fern is the loner. She won't do aything with the others around. I am convinced that she would do better as an only cat. Monte is head "honcho" but Biddy did his best to over throw him when he first got here. Now they co-exist fairly peaceably. Lucas is the cat every cat loves and Calvin is the cat that loves every other cat. Jasper is the one that follows the newcomer around. He has the suspicious mind. And sterling is always the most threatened of a newcomer, but then ends up being play mates with them. Amber is the arrogant one. Actually, she is a snob. Rutherford never has an opinion. etc.
