I have noticed that this little fellows throat will sometimes turn red,it stays almost a light shade of red.this morning it was getting ready to shoot for a cricket and the throat turned bright red.here is the best picture I could get.
I'm not 100 % sure but if he is a panther that may be apart of his aggressive or flared up colors. I've seen other panthers with that red throat. Don't quote me just what I think it could be. And if that's the case nothing to worry about
