I tried the Andrew James New Automatic Pet Feeder and it was shit. It was really difficult to set the clock and the feeder timings, the clock went wrong within hours of being set, it dispensed one meal once then ground to a halt, and it dispenses in fractions of cups rather than proper measurements. And Pete, who is really greedy, really struggled to eat from the feeding bowl. Then I tried a Catmate thing and that was shit too. So I got a couple of Kerbl gravity dispensers and I use those for water and dry food if I'm away for a couple of days, but he does overeat with them.
