What makes you think Red Panda's are agressive? I don't get your point. Red Pandas are cuddly. For clarification, some animals below, which are not cuddly.
Spotted Hyena
Ratel
Well I certainly wouldn't pet one.
Take the Koala bear, nice cuddly and a bit temprimental.
Just because something is cudly, it does not make it harmless.
Something I picked up in my time in voluntary work for the RSPCA.
