She may well be in distress because kitten is missing. She may have been shut away in a shed or garage accidentally and the owners gone on holiday and the same thing may have happened to the kitten. All your can do is put letters through neighbours doors and print out notices and put them on lamp posts, and possibly in the shop windows in your village, if it has any shops. I suppose it's always possible that somebody has taken your kitten but let's hope it soon turns up.
