I recently adopted my first cat and put him on a 3 times a day feeding schedule (1/4 cup breakfast, 1/4 cup lunch, 1/2 cup dinner = the recommended 1 cup on the kibble bag). I used the large portion wheel that was already installed. Before pouring the whole bag of kibble in, I poured 1/4 cup in to see how many portions it filled on the wheel. It filled 2, so I set breakfast and lunch to 2 portions each, and dinner to 4 portions. Easy peasy way to figure out how many portions you need!This has worked well so far, but my scatter brain has been kind of bad about actually keep the correct schedule. Not to mention, I realized that when quarantine ends, I won't always be home to give him breakfast/lunch. This feeder has solved that problem! It also allows me to take day trips to visit family, it will be great when I have to go out of town for a wedding in a few months time! I've got it running on electricity with batteries in in case the power goes out. I'm thinking about using the recording function to record the sound of opening the kibble bag because that's what my cat associates with feeding time.
