Cat-Man-Doo Bonito flakes are among the highest quality flakes on the market and they are derived from a single protein source making them a healthy choice when rewarding your pet. Cat-Man-Doo flakes are larger, moister and have a fresher aroma and appearance than other Bonito flakes. Because Cat-Man-Doo Bonito is high in protein and low in calories with a minimal fat content, it is the perfect choice for our more “robust” pets.
