I've been trying to find some ideas to keep Hermes entertained while I'm away at work. Thus far I've read on general enrichment ideas that zoos utilize but that often includes simulating natural environment. Most of us are trying to do that anyway with climbing material, hides, or plants. I'm looking into getting some form of plant with a mister (on a timer so I can keep the humidity down) to encourage
drinking. Hermes doesn't seem to be getting
hydrated enough via baths and he hates it when I drip water on his nose.
Anyway, I would think anything that might engage them in a natural sense would be beneficial. Trying to encourage hunting by leaving food items around. That works better if you have a larger vivarium. I think a lot of it just stems from them being in fairly small spaces so there is less room to really work with for enrichment purposes. I'll keep my eyes open for anything new and will post what I find.
