I felt that way when my elder cat died at the age of twenty, but it seemed no disrespect to her to adopt another, in this instance a stray tomcat who began hanging around and it was either take him to the pound or take him in. He is a large black Persian mix who resembles Chandlerís Taki and he has an obsession with drinking from faucets.
Oh yes, that's the thing to do. I think it didn't occur to me that I would obviously have another cat that would not be a familiar, and I didn't see how I could go through that again. I had had many cats as a child, and loved all of them, but this one was very different, I decided I really couldn't have that kind of communication with anything but another person after that. It simply didn't occure to me that I wouldn't have had that with another cat. It should have, though, because my neighbour had lost one who was also a familiar and got another one immediately, and he didn't see it as a familiar.
