My house was in very good condition when it arrived, with a minor crack that was easily glued. The paint was very good, and the manufacturer responded immediately to my questions about how to fix and offered replacement parts if i wanted. They were very open to suggestions and corrections. Previous review about short screw to attach roof was corrected, my house came with long roof screws. I chose to insulate roof with foam panel from Home Depot, easy to cut with kitchen knife. We assembled with wood glue and are caulking openings and weather proofing and sealing exterior. We are keeping this house under porch eave until they improve design to make it able to withstand rain from entering the top porch entrance, per my comments to manufacturer as follows:I would like to compliment whoever designed this clever house. However, here are some practical suggestions, which are not a criticism of this fine design, but rather, based upon a lot of experience with outdoor cat housing in snow and rain. This house must be under a porch roof to really be rain proof, but it would be good to make it so it can truly be outside. I think that the idea to make it accessible for cleaning by removing the floors instead of the roof was a good idea, but it doesn't work for this reason: rainwater will hit the top outside porch shelf, and slide into the top floor, getting the pet bedding wet no matter what you do. It will help if you put a low barrier, like a 1 or 2" threshold at the doorway. The cat can still cross it to get in. Because the top floor slides out, there are gaps that strong wind can leak thru. So no matter what, i still think it would be best to go with a sealed upper floor, and make house accessible thru the roof. If a hinge is not practical because the wood could split, maybe you could design the roof as a one piece structure that sits on top with a deep cap, and a ring of weatherstripping or a seal that fits into the house like a cork. You could secure it with a hand tightened wingnut for easy removal. Then just make the floor so you can lift it out to access sealed bottom floor.Also, i prefer to have the cut out opening for the top floor placed next to the window side of house, because any cat bed would need to be pushed up against wall opposite window so cat can look out. Since you located the floor entrance hole opposite the window, That puts the hole where a cat bed need to be, and leaves it unsupported and would cover the hole up. The way it is designed now, the hole must be left open for access, which means the cat has to back up against the window to sleep, and it's harder to keep an eye out for predators. I thought i could just flip the floor panel over to reverse its direction, but because there is the little notch and braces, it doesn't work, unless i do a little construction work.However, i do see the logic your designer employed, because the current design separates the outdoor opening away from the upstairs access hole, providing protection from direct wind or predator coming upstairs. My idea would result in any wind coming in the lower door would more easily get upstairs if you used my idea to move the hole closer to the window side.So an alternative would be to leave the design as is, and move the window itself over to the opposite solid wall. This would be great, but would require the house to be placed with the one solid back wall against your house for bracing, and lessen the ability to back the cat house along its side against a structure. I would be fine with that, as cat house would then stick out long ways instead of sideways, but some people might prefer it as it is for a shallower profile.And finally, it would be good to put a small hole in corner of floor board for access for an outdoor heater plug. Most of us want this to be waterproofed and insulated for outdoor use. You can see how I bought insulation panels to improve roof interior insulation cut to size. This thick panel also solves the problem of the long gap along interior ceiling-roof line, which allows wind to come through. It would be good to insulate the entire house. I would actually be willing to pay more if this work was already offered in a deluxe model.Thank you for a fine product, and being so open to suggestions for improvement, and actually acting upon them.
