Have 2 Border Collies (from the BC rescue pound, though one is really a terrior mutt), we used to have a "great" black cat (a stray that adopted us), straight black velvet so we called him Elvis.
He'd shoot out the doggie door and join us every day that we walked the dogs, lagging behind then shooting ahead, pretending not to "need" to be included in the walks.
The Southern California coyotes finally got him, 1:30 AM heard a bit of a screach, nothing but a few tufts of black hair in the morning (I dashed out with my big flashlight but didn't see anything that night).
Not a dry eye during the "tuft of fur" burial, even among our dogs...
