Interesting. I’ll go hunt around for my picture posting notes and post it here. I use trail cameras on a regular basis. (They are a world of fun.) The picture is fuzzy, but, if had to guess, I would guess that, if it’s not a huge house cat, that it is an immature mountain lion, but probably normal color phase. The coloring is obviously mottled in the photo, which I would guess is an artifact of the photographic image. If one had to choose between the light and dark sections, I would go with the light sections as the primary color, simply because it makes more sense to do so. If I had seen the picture without any context of location, I might have said jaguarundi. Something doesn’t look quite right about it, but I’m guessing immature mountain lion.
I’ll try to post the picture soon.
