Search every day and night. Heat up a can of tuna/salmon/wet food walk around the block waving the aroma in the air, also shake a bag of treats to lure out of hiding. Play cat/kitten sounds from ur cell on your searches. ask neighbours to chk their yard, garages, sheds, under decks/stairs/porch and in window wells. if u can leave a window/door/garage open. best time to look is every night when its dark and quiet more likely to come out of hiding. Put posters up in the neighbourhood.
