Am preparing to open an in-home cat boarding facility. After researching many cat condo/cages, I decided on the Elmo Cat Home. I ordered one to "check it out" and after assembling it (took 3 of us!),  I found it to be just what I need. It is solidly constructed and offers 3 levels for kitty with 2 hammocks and 2 perches. Each level has a "french-type door" for ease in cleaning and accessing litter, bowls, and cat!. Casters are included, however, I am having platforms for storage with larger casters made so I don't have to bend down to floor level to get to the litter box. The condo is 6 feet tall and offers plenty of room for kitty or even 2 cats in one cage. Not sure of the weight limit on the hammocks but certainly a young cat or kitten(s) would love this feature. So I'm ready to place my order for up to 14 more cages as I start my dream of an in-home cattery because I LOVE CATS! Thank you, Wayfair,  for offering such a wonderful product. And yes, I have 3 cats of my own! ZWENY
