Love this cat house! I gave it 4 stars only because one bolt they gave us was threaded wrong at the end and it wouldn't go in all the way. Not a big deal, we just cut it down a little. Also the top of the upper little house comes off very easily when you are unpacking all the parts. There are sharp staples sticking out when this happens so just be careful. Not a worry once you have it all put together and all staples are hidden and won't hurt your pets. Our new kittens are coming in a few weeks and we can't wait to see if they like it. So far our dachshund liked the lower house!
