I was shopping on-line at Bunny Basics & noticed a new litter product. It is called Bio-catolet. It is a wood pulp based product supposedly similar to Carefresh. Bunny basics states that it is light cellulose granules. It is slightly cheaper, but the main bonus would be that it is available in 25-litre size. Has anyone given it a try? If so, is it like carefresh & what are your thoughts?
