Hi David,
I think both sound very good ideas! I have 2 rats and they love to chew and play with cardboard. I also have a guinea who nests in cardboard boxes but doesn't chew it.
In the past, all of my hamsters have chewed, but I think that the idea is still good- -like a temporary/disposable nest box.
I really like the idea of being able to use the packaging of something as a toy.
The bedding idea is really brilliant.I'd definately buy one for my rats.
Good Luck
