The Petmate® Ultra Vari Kennel® is the same durable, heavy-duty construction as our Traditional Vari Kennel but with ultra sturdy wire side panels within our 360-degree full upper surround ventilation. It is designed to be used both in the home , as well as a travel solution. It's easy-to-assemble with tie-down strap holes for a zip-tie installation that adds extra security and an easy-to-open squeeze latch door. The Ultra Vari Kennel provides your pet with plenty of air while they're in the kennel. Ensure safety for your pet whenever and wherever with the Ultra Vari Kennel's heavy-duty plastic shell. For airline travel, the Ultra Vari Kennel meets most air travel requirements. For a smoother journey, pet parents should contact their specific airline beforehand for verification.
