Teenage Guinea Pig
We recently designed a wooden cage for the pigs - it's still being made, so I can't show you pictures. However, I did research a lot about safe materials, and I found out that all sorts of particleboard, MDF, plywood, etc. are a source of formaldehyde gas, because the wax that's used to make the separate pieces of wood stick together is toxic. While the levels of formaldehyde gas that's emitted by furniture is safe for humans, it may not be for guinea pigs, because presumably they'd spend 90% of their time inside the cage, and because they're much smaller. There are no studies that evaluate the toxicity of these materials on guinea pigs, but I wouldn't risk it.
We chose solid birch for the sides, because it's strong and resistant, and the smaller details that needn't be as durable will be made of limewood, because it's cheaper. The cage bottom and front side will be made of scratch-resistant acrylic plexiglass. Finally, the wood will be treated with white-tinted countertop food-safe oil. I really hope it will look nice, but what's even more important is making sure all arts are safe to chew on and live in.
