Unlike typical pet traveling cases that are rigid and slide around the inside of a car, creating an unstable and uncomfortable ride for your pet, this portable travel tube is made of flexible nylon and mesh that accommodates your pet's natural lying position, while safety harnesses secure the travel tube to a car seat for stability. The pet kennel's interior is made of scratch-resistant and waterproof 1800 denier nylon backed with PVC that is easy to clean and the mesh roof provides shade from UV rays and allows the constant flow of air. A sturdy, galvanized sprung steel coil frame springs-open, allowing for easy expansion of the kennel and recoils quickly to store under a car seat. The zippered door folds downward, providing easy entrance and exit for your dog or cat. A handle allows for transport outside of the car and the kennel collapses to 2 1/2". Imported. The large pet kennel adjusts to three lengths: 2 1/3', 3 1/3', and 4', with a 2' diameter. (8 lbs.) For pets up to 80 lbs.
