Blaze King used to make cat furnaces...used to...http://www.blazeking.com/EN/furnace-apex.html.....and are willing to deal with the idiosyncrasies of a cat stove. Some people prefer their appliance actually burn the wood completely and not smolder it; only to let the consumable cat deal with the fuel before it exits the flue. Kinda like with women, some guys like temperamental/higher maintenance women and some, well, umm, don't.
Edit: looks like they are back in production...? https://www.hearth.com/talk/threads/blaze-king-apex-cbt-forced-air-wood-furnace.144440/#post-1948624
I could have swore they were out of production...and I don't recall seeing them on the 2020 EPA cert list
