Take note that many inks used on paper would be toxic to hamsters, so if you were gonna make this i would advise just using plain paper or toilet roll/kitchen roll (with no ink on) i have made this stuff before and as cool as it is there is very little in the finishing product, also there is a risk that the paper could get mouldy when it is drying! You could always try it if you wanted too though, but just be careful!
Hope this helps xxx
