Slow lorises can produce a toxin which they mix with their saliva to use as protection against enemies. The toxin is similar to the allergen in cat dander. 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 suck it into their mouths and deliver it when they bite or lick or kiss. Loris bites cause a painful swelling, but the toxin is mild and not fatal. Cases of human death have been due to anaphylactic shock. If the toxin does not deter a predator, the slow loris will often drop from the branch to the ground and roll into a protective ball.
Just look at it. You want one, don't lie.
