After 5 hard hours of searching, Ziggy found his way back home! We heard a scratching at the back gate- which he normally doesn't use (other gate was wide open). Husband went outside find a neighbor following him saying they saw him and wanted see if he got home safe. What a great neighbor. All the neighbors i met today were very kind and sympathetic. We have a great community. Thank you! And, btw, our gates will be locked until a utility worker knocks on the door to ask permission to enter. Not sure if that's how he got out, but it's our best guess.
