Just got this a few days ago and it's going back. It can't seem to get the amounts 
right. Sometimes it feeds way too much and sometimes way to little. If you touch it, It shoots out some food. or if there is a vibration in the room. I'm sure my cat will 
figure that out soon. Kind of surprised she hasn't yet. Could never leave for a day or
two, because I have no idea if she'll be overfed or starved to death. So .. no, don't waste your money on this one.
