This is a lovely house, good build quality and easy to put together thanks to the clear instructions.
The main issue is that it's quite difficult to access the internal areas without taking it apart. If you cat deposited something in there you'd probably never know until it started smelling bad. It's also tricky to add/ check/ remove bedding, which you really need as the floor on the bottom has gaps in it.
I would buy another but would probably look to modify it with a hatch at the back.
The house was super easy and quick to assemble, I've very excited so far. Looks nice, smells nice of course. Price/performance fit well. Unfortunately the cats have not yet accepted it - although they usually climb into every cupboard, they do not want to go into the cat house... Hopefully that will change soon. Otherwise, I can only recommend it.
