Adopting a stray cat can be a very simple task. It requires that an amount of food be left outside everynight, on your porch. Usually a secluded or private location for the stray to eat in privacy is warranted, in order to coax the cat into the vicinity comfortably. Upon first sighting of the stray eating or being in the vicinity, cuation needs tobe taken not to frighten it away. Small whispers of typical human - cat interaction are allowable, e.g. calling 'hear, puss puss', crouching to its level etc., but take note not to seem to wanting of the cats attention. Repeated sightings of the cat should not prompt distrust between you and the animal, don't pry upon its feeding area and don't try too hard to approach it.
