I've been looking for a better way for my son to carry his guinea pig around, as he doesn't like wearing a sling and prefers to be sitting when he holds her directly. This fit the bill to a tee.
Let me start off by saying that I love that it unzips to flat. It's going to make cleaning it soooo easy.
There are two mesh windows on the sides, which he loved because "it means she'll get loads of fresh air". The front is clear plastic and it unzips separately. The top is plastic with those big air holes, so yeah, more fresh air. It came with two bottom pieces: a sturdy cardboard wrapped in plastic (that's how it felt) and a softer brown tighter mesh one. Since they're not attached, they'll be super easy to keep clean, too. There's a clip attached to a lanyard inside, not sure what for, but I'm sure we'll figure it out eventually.
Overall, it was sturdy enough that the bottom didn't bow at all with our floof baguette in it, and it's pretty, too. We will be using it a lot, and he recommends it to all the piggie parents out there.
