In 1995 we got a 'Rabbitats' brand condo for our lop. Fast forward to 2016 and we reassembled the condo for our newest lop. The condo is a perfect size for a house rabbit, but I was dismayed that I couldn't find that company after 21 years. Walking into a friend's home, I saw a 2-story condo that was similar to the one I loved and it was by Leith Petwerks! We passed the Rabbitat along to our newly adopted rabbit and our lop got a brand new 36-inch Petwerks condo! She loves it!
