Abstract: A versatile pet transporter can be wheeled, carried by hand, or restrained on a car seat. The handle for wheeling is telescopic, retractable, and recessed when not in use, obviating any danger from the handle in a car. Seat belts pass through six different flanges, anchoring the transporter to a car seat in all directions. The transporter may be fitted with a litter box and readily replaceable litter packages, a fan, sound monitoring, and other features.
