Dog and Cat Pet Drive Cage/Tent/Carrier - Pet Twin Cargo This is a pet cargo carrier made overseas (by Sturdi Products). It's a size that allows even medium-sized dogs to relax comfortably. By dividing the interior in the center and opening and closing it, it can accommodate two small dogs or one medium-sized dog. Spring wires are inserted into the frame, making it sturdy, safe, and secure! Plus, it's lightweight! It's perfect for car travel, and pets can also comfortably spend time indoors. It has a name tag, which is very convenient in case of a disaster. It has a structure that doesn't lose its shape when lifted, and the material is 600-denier fabric, which is also used for the bottom of mountaineering backpacks. The front and top have two openings, and the mesh type further enhances comfort! When not in use, it can be folded compactly to about 9cm thick and stored in the included dedicated bag. No tools are needed for assembly; just unfold it! I bought it for car travel, but it seems a bit too big for my two small cats, so I'm going to buy a different one. Thank you very much.
