The isYoung 4L Automatic Feeder is hands down a great automatic feeder! We have had it for over 6 months now. We travel a bit and are able to set up a full week of food for our cat. We have someone check on her daily, but I do not have to worry about her going hungry at her normal feed times. My cat transitioned to an automatic feeder with ease and I was able to set up to include up to 6 meals at specific times throughout the day. I was able to indicate how many servings I wanted at each feeding time. Truly customizable! My favorite feature is that I am able to use batteries with this, so I was able to place it in a convenient location, not immediately next to an outlet. An A/C adapter is also included if you choose to go that route. Overall, I am extremely pleased!
