Rotating enrichment for nocturnal mammals

I’m tweaking our rotation for kinkajous and common genets and want to compare notes. Right now I’m trialing a six-bin enrichment cycle on 48-hour intervals, using anise/vanilla scent trails, mealworm PVC foragers with 10 mm holes mounted at 1.6–2.0 m, and IR checks around 23:00 to confirm use. Have you seen better engagement with daily scent swaps or by staggering vertical complexity, and how are you avoiding habituation without throwing off their dawn/dusk feeding windows?

And for our genets, we saw more use than with daily scent swaps by suspending the mealworm PVC on a short bungee so it oscillates on touch; at about 1.8 m with “10 mm holes” they worked it noticeably longer, and our “23:00” IR clips showed repeat returns instead of single passes. Just mind the tension and add a stopper so it can’t wrap or create entanglement.

We got better use by ditching strict “48-hour intervals” and shifting IR to 01:00–02:00 — our 23:00 checks were missing most activity. Swapping the PVC to mixed hole sizes (8/12 mm vs. “10 mm holes”) and moving mounts nightly helped, and for kinkajous a light banana peel trail beat anise/vanilla refreshed every 72 h. Caveat: smaller holes can frustrate genets; pair with smaller larvae or lighter fills.
