Doc & Phoebe's Indoor Hunting Cat Feeder (formally NoBowl Feeding System) is a complete bowl replacement for one cat. Instead of filling the bowl twice a day, fill and hide the three (3) Doc & Phoebe Mice morning and night. Your cat will hunt, catch and play with many small meals day and night, as nature intended. Decrease anxiety, reduce the instance of scarf and barf, end early wake up calls from a hungry cat, and correct your litter box woes by hiding these easy and fun feeders.
