I would put a bucket or something ON her property where the kitties could come to it and not getting on her property, I would fill it with food for the babies and call to them as you do it... If she IS there and says somethig, explaine to her you thought she was gone and didn't mind feeding them until she got back....adding, "anytime you are gone, I would be GLAD to help out and feed them...".. Is is SO hard having STUPID neighbors who profess to be "animal lovers" I have one and so does my son....
