CUSTOMIZABLE FEEDING SCHEDULE: Our pet feeder is very easy to setup and use! As you can see from our pictures there are 5 individual feeding compartments. Each one holds about 240 ml of DRY OR SEMI-WET food, for a total capacity of 1.2L. The tray itself is very easy to remove and clean! FEEDING ON A REGULAR DIET TIME: This feeder helps you customize pet feeding schedule (use military time). You are able to set regular feeding time in advance and the auto feeder will dispense food for your pets on the right time. Multiple meals for multiple days and up to 5 meals per day. TWO OPTIONS FOR POWER SUPPLY: With our product you have two options for power. If you’re at home you can plug directly into the wall using the DC 5V/1A cable( that is included ) or if you’re on the go you can simply install 4 “C” size batteries (which are NOT included) and our pet feeder can come right along with you! We have also installed a “Low-Battery” warning light that will come on before you run out of power. VOICE MESSAGE CAPABILITY: Our research has shown that if your pet hears the same voice command before each meal, then he or she will begin to associate the two and will know it’s time to eat! The 10 second recording also allows your pet to hear your voice when you aren’t home, which can provide them some comfort from afar! FLEXIBLE STANDBY MODE: We have installed a feature that will automatically set the feeder to “Standby” if there has been no operation for 25 seconds. This will save your money on your electric bill AND batteries!
