You're welcome :)
You could post in some search Comms like the find_buffy_recs, finders_seekers, spuffyficrecs, seeking_spike etc. too and ask for stories.
BTW: Down the Road I Go by Megan_Tam (megan_tam_fics) has in the latest chapters kittens in it (Ch. 19 and in one earlier I think but they don't play a major role). But that was the one I tried to remember.
