Father and son were out fishing and then saw something pretty unbelievable

Kevin Alexander and his son Blake were out fishing on Shasta Lake Sunday afternoon when something caught their eyes.

"We see two things in the water that we had never seen before, so we stopped, turned around for a quick second, and next thing you know we see two large mountain lions swimming across the lake," Kevin shared with krcrtv.com.

The mountain lions swam right by their boat.

"They weren't even intimidated by us at all. They swam right past us and swam all the way across to their side, up the embankment."

"To actually see a mountain lion in the water, it caught me by surprise. I just assumed that cats didn't like water. They seem very very comfortable, they were very very strong swimmers, they were moving a lot of ground really quickly."

Kevin also made sure they gave the mountain lions enough space.

"We certainly respect those animals. Even when we got a little bit close, I was asking him to back up because we understand the power of a mountain lion and what they're capable of."

"To see these mountain lions, it's kind of a once in a lifetime opportunity, and it was really neat to be able to share that with each other."
