The key to this wheeled carrier being different is the Smart-Level platform which keeps the carrier from tipping over when you are pulling your pet from behind.
The Gen7Pets Roller-Carrier comes in three different colors and two different sizes. The small size will carry pets up to 10 pounds and the large up to 20 pounds.
This carrier has straps for use as a backpack or you can safely tuck in the straps for use as a roller carrier. This carrier is also a car seat and a portable kennel. The medium size of this carrier meets most airline regulations.
