A friend of mine says that his brother was deer hunting in south Texas and saw what he described as a "black panther". He said it was a cougar/jaguar type creature that was all black. He said he got a good look at it and watched it as it slowly walked away. He said there is no mistaking what he saw.

I thought there were no black panthers, at least in the United States. What do you guys know about them?
