I purchased this large cage for two kittens I recently adopted who needed a more closed off place at night, seeing as how my house doesn't have doors inside between rooms. 

Putting it together would be easier with two people, but I managed to do it alone after several hours work. Definitely recommend having zip ties to reinforce the sides, as it IS kind of wobbly without those to hold it more firmly. Using black zip ties makes them blend well. 

Now that it is up, the kittens seem to like it well enough that they climb in by themselves and are pretty willing to stay there all night until I let them out in the morning. The pillow-like bed part that comes with it to strap to one of the shelves is very soft and the kittens love that too.
