They seem to be much healthier this time than last. Probably because of the increased food supply (missed birds). Almost impossible to run them down this time. Sawa maximum of seven in one night.

Shot one cat out of the wreck during the day. I noticed in several spots usually near the sooty colonies, holes dug out in the ground in clumps of Lipturus or other thicker plants.
