I wonder what happened after the video. I remember reading awhile back that most people's reactions to these guys is "aww cute!" and to touch and pet them, only to wind up later with pain in their hands from the natural toxins these guys give off. Maybe this one is different.
I don't know anything about toxic lorises, but most mammals that produce toxic secretions get the toxins from their diets. So if a captive loris isn't eating any creepy leaves, it might be OK to snuggle it.
"Slow lorises can produce a toxin which they mix with their saliva and use as protection against enemies. Mothers will lick this toxin onto their offspring before leaving them to search for food. The toxin is produced by glands on the insides of their elbows. The lorises lick or suck it into their mouths and deliver it when they bite. The toxin is not known to be fatal to man, but causes a painful swelling."
That's from Wikipedia, so if you don't like it you can change it.
Yes! I have long admired the slow loris. There is also a "slender loris". And that burning sensation might be their super powerful urine they use to mark their territory.
