I'm not a cat owner presently, but probably will be again when my dog dies (my building is strict about having only one pet). However, I handle probably about two calls a week for litterbox problems, with a behavior helpline (messages) I've volunteered on for about four years now. I'd never seen theses systems you three listed.
mouser, I went to your website link and did some reading about your new system. I was wondering, do you think kittens would get the hang of using the Breeze system? They explain how to make a transition from a traditional lb to the new system, but kittens have a strong natural desire to go in clay. They recommend making a bit of a mix, adding the artificial pellets to the old box as a primary to the transition, but can you go the other way around? I can always call the company when the time comes, but I usually like your impressions on gadgets, software, etc, if you've got some on this.
brotherS, have they got plans for a hyprid roomba/litter-robot that you know of? there's only a billion vehicle jokes that math up well with that gadget.
JavaJones, when I got out of college many years ago, I was finding myself, so I homesteaded my unheated Grandmother's summer cottage which had been unused for several years. I was trying to winterize it, so I bought heat wrap tape for the water pipes, but the bathroom was still unheated, and I was worried about the water in the bowl freezing, and causing a fracture in the fixture. I came up with this idea to bring a hot water pipe up to the intake, and when winter came I would flush with hot water. I sweated the pipe over, with a valve to just use cold like normal the rest of the year. So the first frost came, and I switched to hot, and did a test flush. The house only had a crawl space underneath, and a big iron sewage line underneath, so the combo of the cold bowl, and the steaming water....poof! The whole room was in a thick fog bank, with drips running down the mirror, windows, etc, in just one single flush, almost instantaneously. I'm glad the bowl was very clean and that the flush was a blank test. I went to plan two, drilled a mouse hole through the pine board wall, and brought electricity in there for a space heater. That worked great for many years. Your link reminded me of my big blunder that year, and the laugh I had on myself.
I almost missed this post, but glad I caught it for both chuckles and a possible evolution.
