Thanks Troy. When I looked the model # up online it said it was thermoelectric, but will flip her around and check out her backside. I showed the pic to my wife and told her I was going to look at it and may buy it and she said she liked it. So that's a go from her. If all goes well I will be going to check it out tomorrow after work.

The owner did send me a pic of one of the shelves and they are all wood and slotted. Not sure what type of wood. I will give them the nose test when I check it out.

I REALLy hope this thing materializes. I have 2# of beads but would also add some litter. I don't recall seeing anything about an interior fan, but I have 2 of those Oust fans from yesteryear that I can stick in there for circulation.
