My driveway alarm went off last night at about 1:30AM, and when I went down to investigate I got there just in time to make out a small grey and white form melting into the bushes. So I'm moving the trap down there. The kitten seems to be staying low on the hill near the road, for about a 1/4-1/2 mile length.
I saw his sibling 2 nights in a row coming home at about 1AM, in the EXACT same spot, just finishing crossing the street and trotting uphill into the woods, about 1/4 mile from here. I've left the trap wired open and nothing's touched the food so I don't think he/she's been in the yard.
