Do you ever catch yourself playing favorites with your pets?

I have only had cats, and some cats are more assertive than others, thus getting more of the attention. For example, my two 25 year-olds are twin sisters from the same litter. From the start, Cutie was always eager for attention while Lydia, even when she was still in the boot box that mom insisted on keeping them in, would hiss at me when I came up to them. It turns out that she was fearful rather than unfriendly, but the end result is similar. For some reason, Lydia always thinks I'm going to kill her or something, taking care to walk clear around me. In fact, in twenty-five years, Lydia has only come up by once that I can think of and that was only a few weeks ago. On the other hand, she has safe zones where she feels comfortable being petted, and enjoys it very much. When she is in her cat bed, or in one of the cup-type beds that are on one of her cat trees, or on the top shelf of the cat tree, she very much wants to be played with or petted, and is quite affectionate. When she's on the floor, couch, or anywhere else, she seems to think I'm going to kick her or something. Cutie is friendly pretty much all the time. She brings me cat toys as payment for time, she lies next to me when I go to bed, and she likes to lie behind me on my desk chair, which leads to some painful contortions on my part. But she is always there, so naturally she gets more attention. On my part, I take pains to give Lydia attention whenever she is willing to accept it. Overall though, ever cat is special in their own way.
