While cage was large and would have been good for the rats, bars are far apart and thin. Rats were able to bend bars out of the way and leave the cage when one bar broke.Update: contacted seller and they were quick to send a replacement part free of charge.

I got this product for my two Fancy Rats. I knew there was going to be a possibility of the bottom tray leaving a gap but I ordered it anyway because it’s good quality for a good price and I decided I would fix the gap if it happened. My kit came with all the parts labeled so I didn’t have issues with instructions on putting it together. It took me maybe 30-40 minutes to put it together and I was able to do it by myself. It was really easy. My cage did have a big gap at the bottom big enough for my rats to get through, but I was prepared for this. So I rigged it up and now it’s perfect. This cage is perfect for rats. It’s spacious and affordable. If you have small animals be prepared to rig the bottom tray so there isn’t a gap but besides that, it’s amazing. My rats absolutely love it. It’s 4 stories and even comes with a little hammock you can put in it if you want. It’s sturdy, it looks very nice, it comes with wheels on the bottom so you can move it anywhere with ease, and it’s easy to clean. If you’re thinking of getting it, get it. The bars are small so my adult rats are not able to get through it.

Purchased this for my ferret fits in my room really good, easy to clean, very sturdy, not hard to put up but it does take a little while I purchased the black one and my ferret absolutely loves it.

I like it. Set up was easy even without instructions. took me 20 mins.Worth the money it’s a very high-end cage for the lowest amount of money I would buy it again

This is a great cage for the price! Instructions are a bit complicated but I was able to put it together easy. The only issue is there is a gap between the last bar and the tray. To make sure my son's rat did not escape we attached a bunji cord around the base to make the tray snug with the cage. It worked perfectly!

It’s very spacious, looks cool and it was pretty easy to put together. Like other reviews had mentioned, the bottom/tray does have a bit of a gap, but that was an easy thing to fix. If I ever needed to get a second cage, I would definitely come back to this one!

This is a good cage for my boy rats. Might get a one in the future that is a little bit less fiddly to clean. Only problem is the door is to small.

It took me about an hour and a half to assemble only because the instructions were not very clear so I pieced it together myself. Once I figured it out, then it was easy to assemble. It's a pretty sturdy cage, so no critter could get out through the frame, but the tray on the bottom is flimsy so an animal like an opossum could easily chew through it. The tray isn't as wide as the cage, so there's about a 3/4 inch gap at the bottom that a very small animal like a mouse or small rat could squeeze through. The platforms are kind of flimsy also, so they won't hold a heavy animal. I like that there are two doors so reaching in to clean it is easy. I'm not thrilled with the hammock....it's very thin and doesn't look too comfortable. All-in-all, it's worth the money I spent, but it definitely could use some design improvements.

**Edited Dec 16th to add a photo of the base I had to make myself, out of sheet metalBackground: bought this for my rats! The bar width is perfect and it's big enough to house two adult rats comfortably (maybe 3, but that might get a bit cozy). The only thing that is an issue is the tray at the bottom that my rats will certainly chew through/escape out of (more about that later).Assembly: Based on prior reviews, I knew that this could be a challenge to assemble, so I was prepared for that - and I recommend others kind of anticipate that as well. Even with two professors of technical communication working on this, the instructions were NOT the easiest. We ultimately figured it out, though, and it came together surprisingly well. The instructions totally forgot to mention two bars that go at the bottom to not only secure the tray but also to further secure the screw holding the wheels in place. Luckily, that part of the assembly was pretty intuitive, but it still included myself and my friend going "Yaaaay we're done!" then "Wait, what are those two pieces for?" and looking through the instructions again in vain before just figuring it out on our own.Status of all the pieces: I know that others who've purchased this product have complained of missing or bent pieces, but I think we had one small lip that was a bit bent, but it wasn't anything that affected the overall cage (and we tapped it back into shape anyway with a mallet). Some of the holes for the screws also had a bit of flack inside, but scraping that out didn't take much effort (we just used the little screwing tool... whatever it's called... that was included).Accessories: It comes with three shelves and 3 ramps, and the instructions for those are pretty specific, actually! The shelves and ramps were still a particular challenge. I definitely recommend putting in the shelves BEFORE putting on the top of the case, no matter what the instructions say, because then you get a lot more arm room. That way can also put on the ramps BEFORE putting the shelves into place. Good lord, we just about screamed as those shelves, and if I ever have to put them back in I might cry. Not really an accessory, but the doors are really nice, in my opinion.Biggest issue: the bottom tray is SO DREADFULLY INSECURE. Like, mine falls out. One wiggle and it slips free and falls to the floor. We thought we just had it in wrong, but if we turned it around, then it doesn't fit at all. The cage is square (19 3/8 x 19 3/8 on the inside)... but the tray is not. It's also plastic and even when it fits, there's a gap, and since I'm aiming to put rats in here, I already planned to make my own base tray out of sheet-metal. If you get one where the tray fits better, the natural gap isn't big enough for a rat to squeeze through, but they will definitely be eager to start chewing right there. So I hate the tray, but I knew before I bought it that I'd be replacing/augmenting that.**Edit: I bought some sheet metal, bent it to fit, took the top back off and removed ALL of the levels+ramps, and lowered my handmade tray down in. It's not removable (not without me gutting the cage again and probably crying), but it's massively more stable and my rats will NOT be escaping. So even though the bottom tray for mine didn't fit, it is fixable with a few hours work and $15 worth of sheet metal.Overall: pretty happy with it, having come into this with low expectations. It's sturdy and looks really nice with the dark-grey coated metal, big enough for 2 rats, and my only real complaint is the base tray being so incredibly badly fitting. Could this be because I put something together wrong? Absolutely. Like I said, the instructions were more like general suggestions with photo evidence. I'll try to update once I get the bottom tray re-made and rats in it to give it a real "test drive."
