I've been searching on "cat vs. non-cat", and have found a few mentions of various pro's and con's of each, but by no means a comprehensive, "here's why you want a cat stove," or "here's why you want a non-cat stove." I assume both have their pro's and con's, otherwise one would have by now completely replaced the others. But for a relative newbie, what are the advantages and disadvantages of each? Thanks! edit: I should add that I currently own a cat stove in one end of the house, and am looking for a second stove for the other end of the house. So, I have some familiarity with cat stoves, but none with modern reburn flutes.
