Stray Cats?

A couple of cats have been hanging around our house a lot lately - Turkey Roost Road.  Don't recognize them as neighborhood cats but seem tame and may belong to someone - very hungry and thirsty and fond of milk and leftover turkey!  A photo of one is attached.  The other one is gray and white but is usually chased away by the other one and haven't been able to get a photo.  Comment if they might be yours and I'll get in touch.  Sweet cats but we can't keep them or bring them in due to allergies.
