Red Pandas... are very quiet except for some twittering and whistling communication sounds.
If a Red Panda feels threatened or senses danger, it will often try to scamper up into an inaccessible rock column or a tree. If they can no longer flee, they stand up on their hind legs, which makes them appear somewhat more daunting and allows them the possibility of using the razor-sharp claws on their front paws, which can inflict substantial wounds. Red Pandas are friendly, but are not helpless, and will resist if they feel threatened.
