|Value Line 5 Step Mini Cat StairsThe Value Line version of the MINI variety of BEAR’S STAIRS™ - Cat Stairs is the same great workmanship, but at a value price. The Value Line cat stairs are manufactured from OSB and needle punch carpet. These are less costly materials that do not impact the reliability of the cat stairs. The carpet is thinner than the standard commercial carpet so the screws will be more visible. However, from a short distance away the Value Line looks very similar to the standard Mini Cat Stairs.
