Thanks to the folks who have sent in their Butterscotch sightings. We now have a better sense of his parameters, and a place to set up a permanent feeding station for him. Once we have him on a reliable feeding schedule we can trap him and neuter him! Emily reports that she has "seen Butterscotch passing through [her] parent's front yard ... or else trotting purposefully down the street further south, on a nearly daily basis" so Emily is working on a Butterscotch center. Yay Emily! Big purrs.
She also reports sightings of a gray cat, who she calls Cassius.Is Cassius Background Porch Cat ?
