I am soooo happy that Bo has done so well,and just feels so comfortable at your home.I'm sure knowing you as a family member while she was growing up helped a lot...it was just the sharing that was difficult at first and the way you pat her EVERY time you walk by as well as the others lets her know that you love all equally.
That's what I do...every time i pat one cat...I pat every single cat that sees me.
I do this every day/night.Have done this since the beginning.
I think that's what makes them all get along better.
