any bedding that is more expensive by weight than the giant sacks of rice you can get at a chinese food market is nonsense. <--- my opinion. if bedding by weight costs more than nutritional food that is fit for human consumption, something just cannot be right.
some stuff is just too overpriced, and i would rather invest in good food and an excellent thermostat and good enclosures than to lose money on overpriced bedding. there always is newspaper after all and its virtually free.
