One or two foxes stroll into the camera's field of view and take advantage of my facilities. The clips were taken a few minutes apart, so it may be one fox making a loop around the side yard.
This also explains a chewed-up leather work glove and probably the disappearance of the tree rats.
It's probably a kit fox (Vulpes macrotis) or maybe a small Gray Fox (Urocyon cinereoargenteus). It's hard to tell with the infrared images.
