When I went on vacation in February, someone came in to feed my 4 babies. One is "everybody's cat" and purrs and gives his belly to just about anyone. Mickey is the "seasoned" 7 year old who couldn't care less WHO feeds him, as long as the bowl is full. Lily is skittish and runs and hides but will eventually come around. BUT Little Girl is a ghost. When someone comes through that door that she doesn't know, she is GONE, not to come out until the offender has left, whether I am here with the visitor or not. Hates strangers. When I came home from vacation, I was 'greeted' by all 4 with gusto.
