Zorpupoa 3-Tier Cat Cage Indoor Playpen, Cat Kennel Sturdy Iron Frame withCat Enclosure Hammock Ladder Cat Hammer Toy Balls

This cage was surprisingly easy to put together once I got the hang of it, it took me about an hour to do. I'm using it for two new kittens who are somewhat litter box trained but have trouble finding the normal litter box at night, so now they have a cool little night time home to hang out in with full access to a litter box. The only thing I don't love is the ladder that came with it, it's a little flimsy and they knock it down a lot, and there's no good place to zip tie it down that I have figured out. Hopefully my kittens will be big enough to just jump to each level soon and I can just remove the ladder completely and maybe add a different enrichment activity.
