The classic Shor-Line cage continues to set the standard for Stainless Steel animal housing. By going vertical, this unit gives more openings to house small dogs or cats. The top two cages are 24"W x 24"H, and the middle two are 24"W x 18"H. The 48"W x 30"H double door cage at the bottom can provide space for a larger animal or add an opening with an optional cage divider. Note: The Double Door middle post lifts off easily to slide in a recombinant animal. All Shor-Line cages are 28¼"D.
