We have 2 cats as pure indoor cats. Since we both work, it can easily happen that we come home late in the evening. As previously stood the two Stubentieger howling outside the door. Now there is daily at 6 clock and 16 clock per a dry food ration. The smallest quantity are exactly 40 grams. We take the dry food from ALDI Topic because everything round pieces -not Schnuki that are angular and can block the collector. Round pieces have so far never jammed. Now, after 14 days of continuous operation, I can recommend the very Feeder. Our cats are waiting in the morning looking forward to the clattering of pure sliding pieces. Previously you had always something to watch if you hinstellt the food bowls, because two hungry cats can be very cocky. Now it's very relaxed in the morning. As the delivery is also a good German instructions was, the setting was done in 5 minutes. Set time, choose 12 or 24 Std.Anzeige, enter 1 first day + first Fütterzeit etc. sequentially - or a day at the same time. Then adjust feed ration. Smallest amount about 40 grams - our so get 2x 40 Gr. + Something wet food separately. Machine hums about 10 seconds. Then just slide a few pieces and a little later the rest in the large bowl. 2 cats have enough space here. A siren call can be received. Amazingly clear recording, quite silent - ie because no neighbor frightened. Cats have naturally vigorously trying to help themselves - the machine has won! The cover is fixed! Hardly scratches - very sturdy plastic. Batteries are not included - please order separately! Machine is a little big, but very basic in design. Super: very quiet, here klackert no egg timer as with other machines, large feed pan, is easy to clean, So you can go away and sometimes friends need only look once a day, fresh water and cuddle.
