If the pull of the outside world is strong, there is also a pull towards the human. The cat may disappear on its own errands, but sooner or later, it returns once again for a little while, to greet us with its own type of love.
Most cats do not approach humans recklessly. The possibility of concealed weapons, clods or sticks, tend to make them reserved. Homeless cats in particular - with some justification, unfortunately - consider humans their natural enemies. Much ceremony must be observed, and a number of diplomatic feelers put out, before establishing a state of truce.
