Dear Kasia, We are so sorry that you are having this difficult time! You have been given some excellent advice! Maverick_kitten is right about asking the neighborhood children - they can act like your own private detectives & often know lots. There is an excellent chance that, due to the intense cold, Lucky has been taken inside by some kindhearted person, perhaps a child or someone elderly, who may not actively attempt to find his owner. Keep up hope & keep on trying to find your baby. Even though not knowing what's happening with him is excruciatingly difficult, try not to torture yourself or let your imagination run wild. A candle burns in our window, to show our support for a happy reunion with Lucky & yourself. Susan (&Icy,JC,Joey,Cinders)
