Cats love it, but quality is dubious
We bought this for our cat and she loves it, sleeping inside, on the deck and on the roof.
We removed the plastic flats from the entrance as she didn't seem to use it when they were fitted.
Sadly within about 8 months the roof had failed, the plywood completely delaminated, the ends fell off, etc (not a maintenance issue - no amount of wood preserver will stop the glue in the plywood failing! I suspect the plywood used was not specced for outdoor use). I would not recommend this product for outdoor use.
