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.

Peep Holes are also positioned behind the Worm Hole aperture to encourage play & are finished with the new Black Hot Melt Glue treatment as opposed to Twist Pile fibres.

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.
