The second visit to the water hole was one week later during daylight!
He looked very strong and noble.
He took a very long drink of cool and clean water. Then, he started to walk away, and I saw that he had a serious limp. The water hole has a small stream feeding it, and he had to step over it as he departed. You'll see him limp as he crossed the stream, clearly protecting his left hind limb.
I hope that he's okay. Even a week without being able to kill prey like deer is serious for a mountain lion.
Here's the video, which you can watch here or at Youtube.
