The Worm Hole Shelf aperture is rotated 90º between the Access Holes & comes with a MDF/Twist Pile inserts to place over the aperture to turn it into a Full Shelf.
The unit is a slightly taller 185cm version of our standard SixToo™ because of the inclusion of a Deep Recessed Top.
Ballast needs to be added to the unit to make it Freestanding - we recommended filling the chamber with at least 40kg of sand for a single cat household.
