It took 2 people to put this together, but when completed it was cute and exactly what I envisioned. The directions were easy to follow. One odd thing - there is a door on one end you can open, but when the insulated insert is put in, the door is then blocked. Not a big deal, just an odd design feature. It was definitely large enough inside for 3 cats comfortably (if they like each other). I intend to put a heated pad inside, so will have to drill a hole for the cord to come through the house, but again, not a big deal. Not sure how well this will hold up if it is exposed to weather, but this house will be on my covered porch, so not an issue. My outside feral cats haven't been in it yet, but I think once their curiosity is satisfied and the weather gets colder, that it will be used.
