This type of trail camera photo is becoming commonplace. The silly mountain lion, who I think is a mother who is staying in a very small area, visited a remote camera of mine. Mountain lions stash their kittens in dens, moving them from one den to another frequently, when the kittens are young. Early in the kittens' lives, they can't move too far so the mother will frequent a small area. You might remember that we spotted enlarged teats on this lion fairly recently.
Her behavior is remarkably similar to a mother bobcat's behavior - which I've seen in multiple years in the general area of this camera. With patience, my cameras eventually capture photos of the young cats. However, I've had to move several of my cameras which were in this lion's core area (this camera is outside the "core" area)... so we might miss the kittens this year. But, we can hope!
