Over two million pets and other live animals are transported by air every year in the United States. Federal and state governments impose restrictions on transporting live animals. In addition, each airline establishes its own company policy for the proper handling of the animals they transport. As a shipper or owner, you also have a responsibility to take the necessary precautions to ensure the well-being of the animal you ship.

• Dogs and cats must be at least eight weeks old and must have been weaned for at least five days. Cages and other shipping containers must meet the minimum standard for size, ventilation, strength, sanitation, and design for safe handling.
• No more than 2 small animals, 6 months of age or less, weighing no more than 20 lbs. each, may be transported in the same kennel and they must be of comparable size and weight. Furthermore, the kennel must have enough room for the animal to stand and turn without being impeded. Animals 6 months of age or older must be in their own kennel, appropriate to their size. The animal must be able to turn around and stand up inside the kennel without it impeding or causing the animal to slouch due to size of the kennel.
• Dogs and cats must not be brought to the airline for shipping more than four hours before departure. (Six hours is permitted if shipping arrangements are made in advance.)
  If puppies or kittens less than 16 weeks of age are in transit more than 12 hours, food and water must be provided.
• Older animals must have food at least every 24 hours and water at least every 12 hours. Written instructions for food and water must accompany all animals shipped regardless of the scheduled time in transit.
• Animals may not be exposed to temperatures less than 45°F unless they are accompanied by a certificate signed by a veterinarian stating that they are acclimated to lower temperatures.
• Animals cannot be shipped COD.
