The neighbor said his daughter saw it cross both of our properties, so it wasn't just a fleeting few seconds, and she swore it was a mountain lion. The tracks were too big to be from any dog, coyote or bob cat that I've ever seen around here. I googled on it, and while sightings are rare in Missouri, there ARE several confirmed sightings each year here. They love to eat deer, and we do have deer in our yard quite often. Come to think of it, I haven't seen nor heard coyotes for quite a long time, but the ones I have seen in the past are much smaller than what made those tracks I saw in our garden today.
