For the longest time, Dinah wouldn't have anything to do with Bob. When Pyewacket was alive, of course, Pye was his cat, and Dinah was mine, and while Pye would cuddle with me as second best (except for that period of time when she was trying to kill me), Dinah didn't seem to like Bob at all.
That has slowly changed. Maybe for the last year or so, she's started sleeping in the middle of the bed, between Bob and me, rather than on the outside by me. And in the last month she's started sleeping on his side. And she wants to take naps with him. He said yesterday he was home in the afternoon, and she was walking around on the bed, hissing at him because he wasn't moving fast enough to lie down with her. The hissing thing used to bother him, but now it seems like that's her default "I'm not happy" response rather than something aggressive.
When I say, "Dinah really loves you now," he said, "just in bed," and that does seem to mostly be the case. She loves it when I come home from work and come upstairs to change my clothes. We have "cuddle time," and the three of us lie down on the bed. She can't decide where to lie, though. She'll start out lying on top of me, then go over and lie on Bob, then in the middle, touching both of us. She has also started going under the covers, like Pye used to.
She's mellowed a lot in her old age. As have we all, I suppose.
