If you cannot get it from a main supplier, a great place to pick a large sack up from is a saddle shop, they usual keep it, as its main use is for horses. I got a massive sack for £4.90 and its already proving better than shavings, of which a loave anyways. I used to use a card board like material, cannot recall the name, buy that beats everything, no smells and you cannot even see the poops! But you cannot get that anywhere which is a big shame. But the megazorb is the next best thing!
