Feline Fresh offers an environmentally friendly cat litter made from pine, non-toxic and completely safe for all pets and people, even if ingested. The clumps are biodegradable and flushable, even for septic tanks. When you change the litter box completely you can dispose of the used litter (solid waste removed) into your compost pile or used as mulch in the garden. PlanetWise Products utilizes 100% pine that is a natural by-product of the lumber industry. Feline Fresh is just one of our many scoopable, flushable cat litter options. Contact us for more info.
