Is this the Catmate C50 we're talking about? I do like ours, but always have problems turning the lid to the Zero compartment. And when I manage to do so, I have no idea what I did, or how to do it next time. Tbh, I would prefer a modern electronic one, if there was one that feeds 5 meals. Mind you, this one was around £35, so an electronic one would probabaly be way expensive.
