Removable high quality Kibisan (SAN) kitchen dish material bowl with curved wider food distribution for better kibble access. Important Super Feeder feature: ALL parts in this feeder can be quickly, economically and easily repaired or replaced without disposal or replacement of the entire feeder. * Very compact--can fit under coffee table or other small area. Holds 4 and 3/4 cups of food. Feeder needs minor assembly requiring only a small and medium Phillips tip screwdriver to save on box size (shipping), packaging and possible damage translating into higher consumer cost. * Optional 1.5 gallon (24-cup) hopper available (stackable) available from super-feed or with other combos listed on Amazon. Super feeder accessories are not sold on Amazon. * It can feed kibble increments from a fraction of a cup to several cups of kibbles per day depending on how many on-off programs your chosen external timer or home automation system has. If you can turn on an appliance remotely by phone or other means, you can do that with the Super Feeder. You could even do away with the feeder"s power adapter if you can supply the feeder with 12 to 24V. Why pay for a timer if you already have one. If you do not have one, many different types of timers can be purchased through Amazon or stores like Lowe"s, Wal-Mart, Home Depot, etc... If you do not want to shop for one, you may purchase a Super Feeder combo including a timer of your choice here on Amazon. * This particular model comes with the new improved larger chute opening and tougher polycarbonate chute cover protective device. It will pass up to 5/8" diameter kibbles. Small 1/4" round/square kibbles like offered by Science Diet or other brands are still recommended size for best performance and portion accuracy. Please be aware that although the feeder will not count kibbles (none that we know will), our tests have shown that an accuracy of +/- .1 to .2 ounce per portion weight has been achieved for every two cycles with recommended kibbles. The larger and more oddly shaped the kibbles are (flat instead of spherical), the worse the portion accuracy will be. Most cat food kibbles will work very well, but with so many shapes/sizes of kibbles on the market, it is impossible to predict exact results. Although performance is guaranteed with recommended food as described, please be advised that due to variance of kibble sizes and shapes, 100% portion accuracy simply cannot be guaranteed for all feed cycles and you should be prepared to switch food as necessary if portion accuracy is of utmost importance to you, or you should not purchase the feeder.
