I was very surprised with how light the carrier was in the package. I was also disheartened because the carrier looked fully disassembled and hard to put together. But putting it together was pretty intuitive and I didn't even have to look at the instruction manual. Despite its light weight, it's very sturdy.
Before buying it, I was worried if my cat would have enough space in the carrier, but it seems like it can stretch out and still have space! The photo of my cat inside the carrier is a little bit deceiving, because in person you can tell that you can fit two more cats of my cat's size sitting next to it. My cat is on the smaller side though, only about 15" nose to butt.
