Agree with Cypher. Some things seem nice and natural but can have issues. I think the trick is to make it look like a natural habitat but use conventional safe materials. Moulds can be an issue with damp substrates like compost and coconut fibre which are more for reptiles. A lot of people on here use Hemp or Fitch for substrate - Fitch doesn't look natural as it's white and recycled food grade paper,but hamsters love it because it's nice and soft and they can burrow in it. Hemp does look natural and would be a good option (if you're not allergic to it like I am!).

I would go with compromises - you could have an area of hemp an area of sand, and maybe use cork bark pieces for the natural look (I really like those, and the large cork tunnels - they have an interesting texture for a hamster and can help create different level on the substrate).

Sticking millet sprays in can make it look like there are growing plants and the millet sprays are safe to eat.

The basics hamsters need in a cage/habitat are a good sized house they can build a large nest in - labyrinth houses can be good and they will nest in one room and toilet in another room - a shelf or platform to sit under and to put heavier toys on so they don't sink in the substrate.

Having it looking natural and providing different textures is good for enrichment and variety, but best to stick to safe materials.

If you're picking him up on Saturday (tomorrow?!!!) You will need a cage all set up and ready - they need a couple of weeks without things being disturbed, to settle in so getting the cage right before you put the hamster in is important. If you plan to upgrade later with the natural theme, that's fine but I wouldn't do it too soon.

What might be best is getting the right cage to start with, with a simple set up and then in a few months time, make the changes to the set up.

Did you have a cage in mind? Pet shops do tend to sell people cages that aren't suitable and then the cage ends up having to be upgraded. Are you in the Uk?
