The original cattery building is 8x12, each side having an attached 8x12 wire enclosure with 3 4x8 outdoor runs accessed by kitty doors. Inside, we have installed 6 separate cage areas. Our new girls house is 12x24 with 6 4x6 walk-in cages, with plans for outdoor runs very soon. Both buildings have heat and a/c for our cats' comfort in extreme Texas weather!.
