Do I have a home or caretaker?

Garden City ID

Description

This short hair gray/black/brown tabby with notched ear started sleeping on our covered porch the last 3 nights. I also have an insulated cat shelter but seems to choose our porch chair to sleep. It will not let me approach it (no hissing, just runs). There are a lot of in/out cats in our neighborhood but none that have ever slept the night (11 hrs) on our porch so trying to see if this cat has a home or caretaker (maybe feral from his notched ear?). I have posted to Next-door, Pawboost (which posts on Facebook) and will check with my neighbors. We are off Ellen's Ferry in Collister.
