My Mom and my sisters were out of town for the day, and when we came back, my Dad told us that he was worried because he hadn't seen or heard the cat all day (and that's not like him at all, he's usually very loud and demanding when the house gets quiet). We've searched the entire house and gone around the neighborhood with flashlights looking for him. We left food out on our porch for him, and also moved his litter box outside because my sister found on google that the familiar smell can attract pets. Tomorrow we're going to put pictures of him around the neighborhood.
Can anyone think of anything else we can do? We love Bo very much and we'd do anything to get him back. I feel awful that we never thought to get him micro-chipped.
