This is the best cage ever! A very reasonable price also. I have no idea why I didn't get one of these from the get go of owning guinea pigs. My piggies are so much more happier now, and there is so much more room for accessories and toys. I love that the cage is expandable also so you can add on if you want more guinea pigs. It is so much easier for me to keep clean making my darlings so much more happier. I line the cage with puppy pee pads and then the pink blanket on top. All i have to do in a full cage clean is wipe down the green liner. Replace pee pads and change the blanket. I already clean up poops twice a day. And full clean weekly. So much easier than having to take a whole bottom of a cage apart and emptying somewhere else. But nothing leaks onto the green liner anyway. There is another amazon review on here that someone mentions the cage is flimsy. That is NOT the case. The cage basically comes assembled already, you just have to attach one corner and then put the lining on the bottom which is done with velcro straps on edges. And then the lid onto the top. There are metal clips to keep the top on.) My blankets on top are only there as nights have been cold. It comes off during the day time. I recommend this cage highly. You can also purchase a replacement liner (green part) separate But i don't think i will have to in a long time. My first pic I is the whole cage, the second pic is the clips that go all the way around the top, the third pic is the Velcro straps that the green liner is attached to the cage with, and the Fourth pic is the opening of which you can expand your cage or you can open it if you let your piggies run freely.
