Go around late at night calling them with food. Check around your neighborhood under houses and in small places where they may hide. Put stuff out that has theirs and your scent on it. Hang flyers around for people to see. Check shelters and vets daily. Update chip info if they have a chip and its has not been update since a move. I pray you get your baby back safe and soon.
He's probably nearby. Put up signs and put his litter box outside. Call him and shake his dry food bag or if wet food hit the can over and over while calling him.. Do this for weeks if needed but hopefully you find him soon. Post this on Lakewood and Long Beach Lost and Found Pets and Long Beach Lost & Found Pets if you haven't yet.
Cats do not go far he’s hiding somewhere close look for him late at night when quiet outside put flyers everywhere and most importantly leave your door cracked open as often and as late as you can so he can sneak back in when comfortable often cats find a way back but everything is closed so then go back into hiding
