Smart App Control: The automatic dog feeder connects to WiFi (only supports 2.4GHz WiFi networks), allowing you to program and monitor your pets meals anytime, anywhere through the app ' Life' on your iOS or Android smartphone. You can set up to 15 meals per day with 1-50 portions per meal, accommodating food pellet sizes within 2-15mm. Personalized Voice Meal Call: Our automatic cat feeder allows you to record a 10-second voice message that will automatically play when the meal is dispensed. The familiar sound of the owners voice provides comfort for your pet and ensures consistent feeding. Safety Lock & Mold Prevention: The food storage container and lid of our WiFi pet feeder are equipped with safety locks to prevent mischievous pets from accessing or knocking over the food. Additionally, the sealed environment protects the food container from air, moisture, and pests.
