Canada Bunnies eating newspaper

[Ligio]

The only litter material I can get in my country is wood shavings. Wood shavings are not so practical since they can be really messy and also I have read that are not quite healthy for bunnies. I have found a UK site which ships products to europe so I am gonna be getting Carefresh from there. Until I get the product though, I use newspaper in the litter box as temporary solution but my bunnies are eating the newspaper all the time. Is it safe for them to eat the newspaper? If yes does anyone have any other idea of what to use till I get Carefresh? I have used also hay but it's not absorbent.
Thanks.
