Cunard’s Queen Mary 2 provides regular voyages between the Unites States and England. However, the number of spaces alloted for pets is limited and they remain in a kennel during the voyage, not in the owner's cabin. For those individuals traveling by ocean liner, Cunard should be contacted well in advance for pet accommodations travel requirements, as reservations may need to be made a year in advance.
Pets are not allowed on most other cruise lines, with the exception of service animals. If you are planning to cruise with a service animal, contact the cruise line as far in advance as possible in order to make sure that no problems arise. Most lines require you to provide food for your animal while on board the ship. In addition, some ports of call may have strict regulations and may not allow your animal to leave the ship.
