Hi, all, in a couple of threads recently I mentioned or was asked about this, so here is a photo of the simple mounted bowl I made by cutting down a one gallon vinegar bottle. As you can see, it's been in use for some time. I sometimes toss mealworms or cat kibble into it - it is for dry materials. All the bowls I have tried have ended up turned over or pooped in. Only once in several months has anyone been able to hoist herself up enough to poo in here.
