I have heard numerous stories of cats, who magically find their way
home to their old territories after being moved.  In fact when I was 15
years old, we moved and our male cat used to disappear for 2 weeks at a
time.  We eventually found out that he was going 'home' to our old
house and after 2 weeks or so he would make the return journey to our
new house.  This went on for years with him making the 6 miles or so
trek from one place to the other, by himself.

Now as an adult I have a beautiful female cat (7 years old) and we are
about to move house.  My question is does anyone have experience of
cats who roam to find their old territory ?    Are they exclusively
male ?   I cannot imagine a female wandering off as my own cat will not
go beyond four houses in either direction, preferring to spend 80% of
her outdoors time, in our own back garden, where we have built many
toys for her.    When she stays at my mother's house, she refuses to
put her nose out the door and runs in fear back into the house if we
put her down in the garden.

My cat loves the outdoors - she is mostly an indoor cat in winter but
splits her time 50/50 in summer between indoors and outdoors.   My fear
is that she is so protective of her territory that she may try to find
her way back here, but given that she is a female cat, and they do not
feel happy to wander too far, is this a non-starter ?   Anyone ever
heard of a female cat who travelled any distance in miles to find her
old home ?   I could not bear to lose my baby.
