Kiiro just evolved into Togetchi, as I was expecting. Now I can finally open my mail! (I don't think care slips have any effect on what adult you get but I was avoiding mail just in case, besides it wouldn't be the first time I fill my tama's happy hearts just to open a snake letter a minute later ). I managed to max his training just an hour or so before he evolved. I'm still deciding whether to marry him to a Meme character (to see if I get a different child or Puchitchi again) or to a different family character (to try to get a Mame or Kuchi character).
