Cat stoves require a bit more attention to detail, but nothing that is rocket science. But in my case I decided against it because I knew others would be operating the stove at times and having to explain it all to them seemed like an unwanted hassle. If you are the sole operator of the stove and are confident that you can use it with care the cat does offer some real benefits. Maintenance costs may be a bit higher over time, but I hear varied reports on that as well.
