I’m really happy with this! It is very easy to modify it if you need it to fit in a smaller space, which is exactly what I needed to do. I ended up switching the panels meant for the sides with a panel meant for the front. This made the enclosure narrower so I was able to fit it on my fire escape off of my apartment. There is still plenty of room to walk around it if there is a fire, I’m not completely nuts. I also ended up removing the door and placing the opening right up against my bathroom window and wouldn’t you know, it framed it perfectly! Now I can open the window and my cats can go in and out as they please. The enclosure is very heavy, so I feel confident that it will not move, but I still lashed it to the fire escape just in case. I will most likely attach some mesh screening (smaller opening) to prevent bugs from getting inside and mosquitos from getting to the cats. I love how it turned out! It’s exactly what I was hoping for!
