Can feed from a fraction of a cup to multiple cups of kibbles up to at least 48 times per day with supplied timer. Tamper-proof feed adjustment under rubber plug! Various home automation systems even including webcams can also be used to operate/monitor the Super Feeder. If you can turn on an appliance remotely with phone or other means, you could do that. All parts in the Super Feeder can be easily replaced! * The Super Feed special analog timer has an LED light to show you when timer is on, a facial outlet for better access. and tiny "on" tabs (one for each feed cycle) that will provide for up to 48 daily feed cycles. You can use your own digital timer, purchase the Super Feeder ACDT-20 digital timer or use a home automation system to operate it. * Ready to mount to supplied mount/platform--size of unit is 12x11x21inches tall with one clear 2-cup extension installed (of the two supplied) as shown. You can also mount the feeder to a wall or cat play stand if not using the stand to guard against that really wild cat! Lots of other ways to mount it if needed. 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. * NEW polycarbonate clear extensions now guaranteed for life against breakage under normal use! High-quality dishwasher safe Kibisan® kitchen plate type material bowl with bowed splitting dish for wider distribution of kibbles creating better access to food. ALL parts in this feeder can be quickly, economically and easily repaired or replaced without disposal or replacement of the entire feeder. Use the basic feeder by itself, or if you need it when going away, a 1.8 gallons capacity (24 cups) hopper is supplied. The Super Feeder"s unique large hopper design will not allow kibbles to bridge inside, a very common occurrence in many other feeders where someone has to occasionally "jolt" the feeder to loosen kibbles that have stuck together preventing the unit from dispensing them properly. It can also be mounted to a wall or cat play stand using a piece of 2x4 instead of the supplied short stand to guard against that strong mischievous cat! Lots of mounting options are available with this very unique feeder. * 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.
