This softwood based cat litter will soak up odours, and it is also biodegradable, so it is good for eco-conscious cat owners. It comes in the form of 30-litre bags of wood pellets, and so it contains enough cat litter for a single indoor cat to use for around a month at least. Made from natural materials, it is environmentally friendly and gentle on your cat's paws, to which this litter will not stick.
