Anotec is a non-toxic, biodegradable deodorizer that eliminates the odors associated with small animal confinement. Anotec chemically bonds with odors to eliminate them - not mask them with perfumes. Anotec can be applied directly to surfaces or used as an air freshener. Use Anotec on a regular basis in your rabbitry to neutralize ammonia and other odors that can lead to respiratory distress and disease. This product is a 16 oz. bottle of Anotec concentrate. Since Anotec is non-irritating and non-toxic, exact concentrations are not critical. That makes it ideal for you to dilute to your preferred strength. It is also available in ready-to-use pump dispensers.
