Whether you’re home or away, you’ll appreciate the well-planned features of this automatic feeder. It dispenses food quietly and slowly to discourage gulping that can lead to bloating. The see-through container has an airtight seal that keeps food fresh. Medium and large models also have an agitator that mixes food regularly to prevent it from getting stale. Digital timer can be programmed to dispense food up to 8 times per day. Battery backup protects settings but AC power is required to run feeder. Bowl detaches easily for cleaning. Protective stainless steel sheathing on power cord for safety. UL approved.
