Cody came first, then Greta. Cody was an intact neurotic male bully. Having him neutered really didn't make him any less neurotic and he was a bully for years. Greta avoided him.
Last year though, when he got sick, everything changed. Although better now, Cody is not top male in the pack-right now Moonie and Oliver share that role. It depressed him for awhile, or so it seemed. Now he and Greta hang out like an old retired couple. She has her bad hip, and he's just old-and the groom each other and care for each other like they've been friends for life.
It's like the song says "if you can't be with the one you love, honey, love the one you're with."
