Happy Ferret Bio Litter Bio litter fully meets the requirements of the conscientious pets owner both in hygiene and environmental considerations. Advantages: Dust free, economical and extremely absorbent. Bio litter, which is made of cellulose waste of the hygiene industry (nappies, paper, cardboard, etc.), is free from dust (no sneezing) and will absorb 3 times as much liquid as regular litter. Owing to the very fast absorbency (5 sec. 137%) the toilet remains dry. Safe absorption of odours - smells fresh - Natural active scent substances in the cellulose pellets will capture the odour molecules (urine) immediately. Hygienic light pellets are clean, smooth and easy on the paws. No problem with waste management - 100% compostable - anti-bacterial.
