This is a game I'd actually found once before, back when it was just starting, but I forgot how to get there... :/ ... BUT, thanks to our friends at HentaiPalm, I can now provide a linky.
http://www.papurukoneko.com/master/I haven't played it in it's newest form, but from what I remember it's a somewhat more limited version of SlaveMaker, with a single catgirl. It was pretty rough last I knew, but still playable even then. I'm sure it's been improved since then, so it's probably worth a look.
