Our window was left open too much and he snuck out that night. We have put up posters around our area and have posted online on Nextdoor. We have several neighbors that walk their dogs and they have been on the look out for me. We put his litter box outside with hopes that he would smell his scent and be back. As of today we still haven't seen him. Is there a way to search his micochip and see where the location is? I have researched and found that sometimes cats come back months after they leave and have hoped this will happen. I am losing hope and not sure what else to do.
