I believe the 18x28x36 is the vision 332. I ordered two of those exact models from LLL. They are nice cages but can be a little bit cumbersome and the lips on the front of the cage make them a little hard to clean out if you use aspen, cypress etc. (in my experience). I dont keep my ball pythons in these cages, i have found that 41 qt tubs work best for me to house the ball pythons. Im not using the visions at all at the moment, but planning on moving a boa i have into them when she gets a little larger.
