A NEW FRIEND

I have been told that during The Great Depression of the 20th Century (late 1920's/early 30's) that many who had fallen on really hard times would stop at farm houses to see if they could work for something to eat.
And I have been told that if they came upon some kind folks who would give them a good, hot, nourishing meal, that they would mark a fence post with a mark that others needing a hand out would recognize as a good place to stop.
Do you think cats have that same sort of system!

She's been coming around quite often and seems to be more interested in a friendly "Good Morning" and a bit of petting than she is in a bowl of cream.
Haven't invited her in yet, but do stop working in the garden long enough to give her some personal attention.
Seems to be working out as a pretty good relationship so far.
Have a great week.
