This pet food feeder is fantastic!! It uses Bluetooth and WiFi to connect to my phone from anywhere. I can set up feeding for once a day, or several. I can choose how much for each feeding. You can also give a snack from anywhere. It’s a nice big bowl and holds about 24 cups of food in its tub. It’s great to be able to leave home and not have to worry about who is going to feed the cats, and making sure you are not over feeding them.
