Comfey Pet Premium Wood based Pine Litter is made from pine shavings from saw mills. The shavings are ground and pelleted to form a light, highly absorbent cat litter. No trees are chopped down to make Comfey Pet Cat Litter. It is efficient recycling of a by-product from timber grown in sustainable forests with replanting schemes. Comfey Pet Cat Litter can be dug into the garden or composted. It can also be flushed down the toilet. This litter is up to three times more absorbent than other litters so you do not need to change it as often. Comfey Pet Cat Litter naturally controls odours effectively keeping nasty smells at bay. It is thoroughly dust-extracted to produce a clean pleasant product to handle.
