Since my buns have cages with plastic floors sometimes I line with newspapers, other times I jjust put down a thin layer of baking soda..the baking soda acts as a deoderizer. Please go to www.rabbit.org and read up on litter....sawdust and pine and cedar shavings are not good bedding for rabbits....their urine mixes with an oil in the soft woods and can cause a cancer causing vapor. Yes, it takes several years for the cancer to develop but is it really worth the risk?

Have you been able to join the Tufy Forum yet? Those UK gals will be happy to give you advice on what they use for litter.
