TIAKI Verde Transport Box

The carrier in size S easily fits a small cat or a cat of a small breed. At the moment, I'm using it for guinea pigs. Unfortunately, size S only fits one guinea pig—mine like to have plenty of space. A huge plus is the opening roof. The carrier is easy to assemble, well-made, and at the same time lightweight. It's easy to clean, fits on a car seat, and you can secure it with a seatbelt without any problem.
