I woke my one panther trying to get him back in his enclosure last year. He proceeded to bite the hell out of me. Not just a nip, but got in between my fingers as hard as he could and was thrashing for a good 30 seconds, I thought for sure he was going to get a chunk out of me. I had the V shaped bite teeth marks for a week after that lol. Was all my fault though, I startled him in the dark while he was asleep, don't blame him at all for it.
