Kaytee Red Cedar Bedding is ideal for small animals, cats and dogs. An all natural biodegradable product, Kaytee Red Cedar Bedding naturally repels fleas and many other insects. Cedar logs are specially processed to eliminate much of the dust and other wood debris found in other cedar beddings. Aromatic cedar oil may produce skin problems in certain sensitive animals most frequently guinea pigs, and hamsters. Should be used as a non-contact bedding. Use only in well ventilated cages, not recommended for closed environments, such as habitrails or in aquariums with limited ventilation.
