1. Hygienic Design, Fully Dismountable and Washable All parts (duck body, food container, moving parts) are dishwasher safe (recommended temperature below 60°C). A special antibacterial coating (SIAA certified) inhibits mold and bacterial growth. Chewresistant reinforced ABS resin (thickness 3 mm) is also suitable for large dogs with chewing habits. To prevent accidental swallowing, the diameter of the moving parts must be at least 4 cm. 2. Dual Function: Intelligence Development and Feed Management The food gradually comes out of the duck's beak, and your pet earns food while solving puzzles. You can switch between automatic feeding at 15minute intervals (up to 5 times adjustable) and manual mode. The educational effect helps relieve stress in dogs and stimulates the hunting instinct in cats. 3. Multiple Opening Sizes The size is 22cm x 11cm x 14cm, with three sizes of hood openings, suitable for pets of different sizes—from small cats and small dogs to large dogs—to meet your daily needs. 4. Promotes the Joint Growth of Children and Pets The puzzle pieces are designed with safety in mind (diameter 4.5 cm or more) to prevent toddlers from operating the bowl incorrectly. It serves as an educational tool that fosters responsibility and respect for life by encouraging children to refill the bowl. The transparent observation window allows you to visualize the dog's eating process.
