Segelkatt July 31, 2018 I purchased an Our Pets automatic feeder from Amazon mainly because I have one particular cat that should drop some pounds. The other 3 cats have on an RFID on their collar which opens the lid when one of these will come inside of two toes. https://pet-shop-dubai-hills-mall58023.wikistatement.com/4852086/cat_food_an_overview
