I originally thought deer, but then questioned it after comparing the heights of the animals. Even though the second animal is a bit farther away, it seems smaller to me, and I keep thinking my brain is recognizing a long tail, though you cannot see one on slow/stop motion.
This is the same location I captured a pretty good size cat on the cam about 3 months prior, which was posted in the camera/trail cam section of the forum. The fact that it comes out of hiding just second after that other deer strolls through made it seem more sinister than a deer, but God knows, those deer are skittish as hell. I have many videos of them standing still one moment then at full throttle the next, for seemingly no reason at all.
If I hadn't deleted the prior video, I might have been able to visualize the animal before it bolted.
Thanks for the input.
