Many scientific studies supporting the advantages of diet optimization have been published in scientific journals for more than 40 years. Our 7-day Carousel Feeder™ provides diet optimization every day of the week. Individual 25-gram wells allow a one week supply of accurate daily food allotments. Each well includes a label indicating the day of the week. Daily access to a pre-measured food portion is renewed by turning the carousel. The stainless steel and clear polycarbonate design is easily cleaned and fully autoclavable. Feeders may be stacked for handling and storage and may be filled with a semiautomatic filling station.
