Petique Happy Camper Pet Carrier has a unique design that transforms a pet carrier on wheels for a smooth 360-degree ride to transforming into a well-ventilated house with four expandable sides! The spacious pet carrier helps reduce your pet's stress and anxiety while giving them more space to stretch and feel comfortable. With four extendable mesh sides, your pets can move around freely, broaden their view, and increase air circulation while staying protected inside. When you think traveling with your pets has never been more convenient, the Happy Camper Pet Carrier provides three essential carrying options to carry your paw-tner around: The telescoping handle to smoothly roll them around on four wheels, carrying them using the comfortably padded shoulder strap, or carrying them using the durable top handle straps.
