Please check the shelters daily with a photo. Calling does not work as so many cats look alike. Put flyers up and check with your neighbors kitty could be stuck in a shed etc. get up during the night and open all outdoor entrances and call for kitty. Go out at night and check around in all bushes with a flashlight. Contact a rescue group to set a trap with food. Needs to be checked often. My neighbor trapped her cat at 2 am so it works. Good Luck hope you find your beautiful fur baby. Keep looking and don’t give up.
