Ive had cat feeders in the past, but my bigger cat Nimbus always somehow managed to knock them over. Im glad I finally found a feeder then not only has a click lock system on the top, but sits on my shelf to wear my cats cannot mess around with it. Set up was pretty easy, just read the instructions well (Spelling and grammar needs to be rechecked but youll understand it). The app is easy to use and let me set up up to 6 feeding times. I would recommend hitting the serve portion button so you can see how much is served so you can figure out how many portions need to be dispensed. I have the first portion starting at 3 AM because their last feeder started at that time; shoulda gotten this thing sooner! Ill update as we go (:
