Do this ASAP
Put out items with your scent on it, like an item of dirty clothing, towel, blanket, sneakers. Put vacuum dust outside since It contains home scents in it. Leave out a bowl of water. DO NOT put litter box out it will attract predators. Call as may times as possible, but night time is best Because its quite. Ask neighbors to check garages, sheds and under decks and their security camera recordings in the mid morning hours since cats are more likely to come out when it's quiet during the night. Put up 11x17 poster in neighborhood.
Use a flashlight at night because you will see the reflection of their eyes.
Shake treat bag as often as you can. Post on Nextdoor Neighborhood app and your local town community page..shared
