Federal regulations require that each crate be properly labeled with the words "LIVE ANIMAL" on the top and at least one side of the crate in 1-inch (2.5 cm) letters. The crate must also have orientation labels. Indicate the top with arrows or "This End Up" markings on at least two sides.
Certification and feeding instructions
United is required to attach a certification to the outside of the crate that states the last time the animal was offered food and water. This certification must be signed by the customer and include any special feeding and watering instructions.
IMPORTANT: Do not feed your animal in the two hours prior to departure, as a full stomach can cause discomfort for a traveling pet — including stomach bloating and vomiting, among other conditions.
Contact information label
Label the top of the crate with your pet's name as well as the names, addresses and telephone numbers of those who will be dropping off and picking up your pet. Federal regulations require that each crate is labeled to safeguard your pet.
