I don't see much gear laying around, do they mess with you at night? Spent a night getting harassed by a Ringtail Cat and these remind me so much of them, for obvious reasons.
No, the ring-tail lemurs are diurnal and don't run around at night. Not much goes on at night in terms of messing with our gear. Once, a team-member had a boot stolen from outside her tent by a stray dog. We found it chewed up in the forest the next day. We keep our gear in the back vestibule (or in the tent) to be safe, but it's never really been an issue.
I could defo see a ring-tail cat being a total **nt at night and messing with stuff.
