I am trying to create a 'natural' looking hamster cage. I want to create as much enrichment as I can by using rocks, moss, wood, leaves, sand, dirt and other elements that would be natural to a (dwarf) hamster.
I've seen cages with plants in them but I'm not too familiar with plant species so I have no idea what would be safe for a hamster if he decides to eat it.
A lot of herbs would be safe but I know my hamster dislikes the smell of some herbs (mint and basil) so I don't want to annoy him with that constant smell in his cage. The plant does not need to be tasty/likeable for him but I'm fine if it is, I don't mind replacing it from time to time.
Next to that it will not be in constant direct sunlight as I do not want to expose the hamster to constant direct sunlight. There is natural light in the room and cage however.
