I can't see us ever being totally catless either. There are some days they keep me going when I just want to give up.
That's pretty much the way it is here, too. I think that, as these kids pass on, we won't be getting other cats. It's not that we don't want them, but our budget probably won't allow for them the way it does right now. I hope that makes sense.
OTOH, Rick has often said that he doesn't think we were ever be totally without cats. And I have to say that I can't really envision our lives being catless. Simply put, cats just have so many ways to enrich our lives. But maybe just two.
