I can't deny that, in a lot of ways, having only one cat is a heck of a lot easier. I can get up in the morning (or, depending on my shift, the afternoon), dump some food in Vir's bowl, and then just walk away. No need to stand there between two cats while they eat, thwarting their constant attempts to steal each other's vet-prescribed food. No more claws-out scuffles over who gets to sit on top of me when I'm sprawled on the couch reading or watching TV.
But it's also rather melancholy, of course. I suspect it's going to be a while before I stop thinking I hear a noise and turning around to see if it's Nova about to jump up on my computer desk, or feeling a pang when I put an empty cereal bowl into the sink instead of onto the floor for him to lick.
