Pros and Cons. Pro: The materials are a good quality and it is an insulated house and roof. Not too difficult to assemble and no tools required. Looks very nice. Has a "windshield" over the door which is split up the middle making entry/leaving easier. Great awning over the door. Fairly sturdy, but I don't think the roof could sustain heavy logs falling on it. Also has an escape door with insulated flap which is wonderful! The roof is well attached with velcro flaps but is easy to remove to clean, etc.
Cons: It does leak! I put it together properly and we had a good rain and when I checked the inside it was very wet! Also, it sets on a metal frame that the base of the house attaches to with velcro flaps, but the frame was about 1/2 to 3/4 inch wider and longer than the house so that the flaps to attach it to frame only reached the velcro on one end and side and I had to use heavy duty duct tape to attach the other flaps to the velcro. Another issue was when assembling you put the metal frame together which was not hard if you follow the enclosed instructions and then attach the house to it. But the house kept folding in on itself and though I managed it would have been easier with another person helping. I got the extra large (with the gabled roof) but I think only two small to medium cats could fit in it and that might be a little cramped. Another issue I had was one side of the plastic door covering was scrunched up and would not straighten out; however, hotter weather caused it to flatten out so now it is fine.
I did contact the seller about the leaking and frame size and they responded quickly and sent me another house. Great customer service! Haven't put together the other house yet, kind of assuming it may have the leaking issue and want to get a heavy duty tarp to put over it first.
