Former ferals somehow become some of the most bonded cats it seems, @Nifty-Chicken . I had the opportunity to work with a few true blue ones while at shelters, then adopted two myself! When they're young like your "Caly" appeared to be, it's so much easier to build the bond because they're still...
I'm just now catching this thread, @Nifty-Chicken bravo on you all for taking in these feral kitties needing a home and a job of great skill. I've had a few "formerly feral" cats over the years and they can make such great companions.
