I have this Melamine Cage I made and ended up not using. Here are the specs:
48 wide x 16 deep x 16 tall appx.
1/4 glass sliding Doors
Comes with sliding glass door lock and heavy duty casters (wheels)
The wood litterdam is whitewood with 3 coats of water based poly and cured.

I can include 2 feet of flexwatt with the deal, but I never had the chance to actually install the flexwatt in the bottom. I drilled some holes for ventilation and I have two ceramic tiles I was going to put over the flexwatt and silicone to the bottom. Just didn't get around to it.

$100 or best offer (which is my cost for the materials alone)
Pickup only in Parkersburg, WV area or
