Update on feral kitties:
Adopted out (white) with her new brother, very happy together:
All babies (4) adopted... still have feral mom cat and her sister (also up for adoption) but have removed the baby gate from the nursery (back bedroom) and giving them full run of the house and catio. They seem to be blending with our three large cats (a little hissing but no fighting).
Biscuit joined my wife on the couch the other night:
Marie (mom kitty) is doing well also (old picture from when she as still living outdoors):
