I know this is an old post, but I didn't want to start a new one on the same topic. I have a Super Pet glass water bottle for Buddha, but one day, I noticed him licking at it for a while, so I checked it and sure enough, no water would come out. I got it working, then he drank for a long time and I felt bad that he had gone for a bit without water. I went to PetSmart yesterday and got two of the Lixit flip-top water bottles. I've seen him drink from at least one of them, but I'm not sure if he's got the hang of it yet. I checked it with my finger and it definitely works - I'm just not sure if he knows how to work it. I put the Super Pet bottle back up, so now he has three water bottles, so he should be fine, but I was just wondering if anyone has had success with these Lixit water bottles long-term? They don't leak, which is nice - the Super Pet got low pretty quick, but I think it's because half of it leaked out. I'm just worried about him getting enough water.
