New Family Steppin' Out!

A couple of posts ago, I introduced this small family, which arrived on March 31st.  Here they are, still in the (safe) introductory cage, up high in the living room, getting the lay of the land.  After a few days, they were moved to a big back room with plenty of windows, cat trees, etc., where they stayed until a few days ago, when I began leaving the door open to the rest of the house. (cat door locked in the 'out' direction for now) They made a few quick and timid forays out, but yesterday...!! All of a sudden they were all over the house! Mind you, up to then they had mainly huddled inside a tiny condo in the back room.  Mother Julia had seen fit to lie on top of the big cat tree, but daddy Jules stayed hidden 99% of the time. What joy to see the switch flipped...and so quickly! They explored the whole house, said howdy to the other cats, rolled around on the floor...Go Figure! Always a surprise, with cats! And what a happy one! I had worried that they would take forever to learn to trust us, to be comfortable in this new environment, but no! Our dear Bruna, who came last April, has only last month started going into the inner bedroom...took her a year to leave her first room...glad it had a window seat with a view... We still can't touch her, but she lounges on the bed, grooms and is groomed by the others...and has two new views.  At night she does roam the house, while we're safe out of her way, asleep. 
The new family: I had feared that they'd been badly neglected, or abused. They were totally passive... did not express any frustration, anger, or resistance to being in a new place, being picked up, etc. Most unusual, They did not seem frightened, just paralyzed, made uncertain, by our presence. 
They're all "home"now, sleeping. When they get up and about again, I'll take some more photos of them in action!
