Good in general
These are great feeders. They've always opened. I have several cats so these would be so much better if they were digital. The bowls are removable so easy to clean. My cats push these around so if they push them under something, a radiator or kitchen unit for example, this could prevent them opening fully. My biggest gripe is the ice packs, good idea, however I used them for the first time this week and cats removed one of the removable bowls, then chewed and punctured the flimsy ice pack. There is nothing in the information leaflet to say what this fluid contains. I will never use the ice packs again.
