Arianwen, I'm relieved that you think so, because I was disappointed by that part of the article. I may be wrong, but I think cats do derive comfort from the presence of other cats, and even if they don't get along!! Maybe it's what I'd like to think, I don't know. Stray colonies do defend each other and the colony from stranger newcomers, I see it everyday in my colony downstairs. And when there's a fight, it's VERY clear who each of them sides with. Cats do have friends among other cats. They tend to prefer some cats over others, same as we humans do. They take long to make a new friendship with a cat they've known a while sometimes, and then they become friends. I've seen this in my colony. But they are a lot more individualistic than pack animals, preferring to do their thing if there's something they feel like doing at a certain moment, rather than stick with their friend.
