For your pet’s safety, secure the inside leash to your pet‘s collar or harness and strap the carrier to the seat of the car while driving. Pass the seat belt’s waist strap through the two loops or pocket flap in the back of the carrier and buckle up. You may also use the car seat strap (available in Accessories page) to strap the carrier around the back of the seat. For birds, please close the front window mesh. All 2006 Celltei® carriers, with the exception of the open-top design, can be strapped to a car seat.
