This is a very nice little house. My cats love it.It’s pretty easy to assemble. I used a drill. I think it would be harder if you only have a screwdriver. I pretty much did it alone except I did need help with the roof. It’s too bulky to set it up by yourself. The one issue is the hinges that separate will come apart when you try to move it so you have to be careful, or just get it where you want it and then put the roof on.I give it 5 stars ⭐️ and my cats love it.It’s been a while since I posted and it’s still doing great. The top piece has warped and is splitting but I think I can fix it. My cats love it.
