they sorta look cute but they are nasty. at least they are slow, generally you are only gonna get shredded by them if you are stupid. really they are the australian progenitor of the sloth, who is at least big and a bit less stupid.
possoms, on the other hand, again you have to be stupid, but they will shred you also, even when they don't mean to. possoms and ferrets have a lot in common in this way, except ferrets bite you more, whereas possoms might just want to grab onto you and put their very strong claws straight into your arms 3-10mm deep.
