CareFRESH is the one that started it all, the first pet bedding made from virgin reclaimed cellulose. You'll love CareFRESH because it's absorbent and controls odour. It's also all natural and biodegradable. The CareFRESH formula is free from contaminants like pine or cedar oils, so it is safe for your small pet. (Aromatic oils in pine and cedar bedding have been shown to have adverse health effects on small pets.) Plus it provides a more natural living environment promoting instinctive burrowing and nesting behaviours of small pets.For odour control and absorbency, choose CareFRESH Ultra bedding for Ultra soft, Ultra Clean and an Ultra absorbent bedding for your pet.

CareFRESH Ultra is a great value, too, since it's long lasting and requires fewer changes. Its patented formula is free from contaminants like pine or cedar oils, so it is safe for your small pet.
