The video is too grainy to be sure, but from the size of the head and the apparent tufted tail, it certainly looks like it could be a “real” lion, a female one.
Shape of the head also. I was able to see the video at a different link. Could have escaped from a private owner.
The gait and the way it holds it’s tail says it’s definitely a large cat of some kind. I agree, the head is shaped like a lioness.
That’s what I think too. Looks like a lioness.
