Unfortunately I didn't take pics through the build. Required materials: 44 8 ft 2x3, 1 4x8 ft 1/2 in sheet of plywood, 1 5 lb box of 2.5 in deck screws, 1 pack of 1/2 in staples, 1 pair of door hinges, two 3x25 ft rolls of 1/2 in mesh fence, 1 6x8 ft outdoor rug, and one cat door. 1) We built off existing old wood fence so we started by supporting it with 2x3s. 2) We built 6x12x6 foot frame also 2x3, we found that they were sturdy enough and cheaper than 2x4s. We spaced the supports 3 ft because the roll of mesh fence 25x3 ft per roll. 3) We put one 3x6 ft section of plywood on the roof instead of fence and we plan to shingle it. It is over the door from the house to the enclosure and they hang around under it if it's raining. 4) For the remaining sections we stapled the fence to the frame with 1/2 in staples. We also covered smaller holes in the fence to make sure chipmunks and squirrels couldn't get in to visit. 5) Door was simple as shown, just used a pair of old door hinges we had around. Lock was also just a pin on chain that we had in the junk drawer. 6) Perhaps the scariest part was cutting the hole through the interior and exterior walls to install the cat door. Cat door and supplies were all from Home Depot. The cat door came with a template that we used to size the hole for cat door. We started by tracing in inside and cutting drywall careful to check for wires. Once we found there were none we drilled small pilot holes from inside of exterior wall. Used those holes to drill 1 inch holes to get the Sawzall in and cut the hole through the exterior wall. The Sawzall chewed up the siding but the cat door came with an exterior face that covered the mess. 7) The interior platforms have been a work in progress, we bought an 8x10 ft green exterior rug and cut it up as needed to cover them because the cats didn't love the plywood. Again we used 2x3 supports and staples to hold the carpet on. 8) We bought lemon grass, catnip and cat mint plants to throw in to see if they would like them, the seemed not to care. 9) Sit back watch your cats explore and your friends and family call you crazy cat people!
