I fed a stray cat for a good year once... I called him (of course, it could just as well had been a she) Pilgrim. A beautiful cat, never let me pet him One day he just stopped coming and I never saw Pilgrim again... Still brings tears to my eyes thinking bout it.

Anyways, I'd just be on the lookout for the cat... It might try to come back tomorrow at the same place, same time. Maybe even put out food and let it stand outside the whole time if it's a possiblity for you.

Good luck!
