I live in that neighborhood – Shepherd and New Hampshire. I have three orange tabbies, all outdoor cats, but all mine are collared. I’ll keep an eye out for yours.
For locating a lost cat – they tend to stay within a block of the house. You should start doing a grid search – ask you neighbors to let you into their garages and yards. he may be under a porch, or in a garage, unable to get out or hurt. I’ll pray for Mo, and let us know if you find him.
