The present invention discloses a pet carrier wherein the ,pet carrier is evenly perforated with ventilation holes. The pet carrier comprises four non-separable flexible panels: a bottom panel, a first-side panel, a second-side panel and a roof panel, in which the first-side panel, the second-side panel, and the roof panel can be folded onto the bottom panel to form a collapsed configuration. And the second configuration utilizes a continuous dual-directional zipper stitched along the perimeter of the four panels which can be connected together to form a three-dimensional enclosed carrier. This simple, lightweight and portable carrier allows for easy transportation and storage. The allover perforation of the pet carrier maximizes ventilation and breathability of the carrier thus reducing the risk of suffocation of the pet contained inside. It also serves the purpose of alleviating stress and anxiety of the pet by increasing comfortability and visibility of the exterior surrounding.
