The CAT Ferry travels between Portland, ME and Yarmouth, NS in just 3.5 hours. RVs, pickups, SUVs, cars, tour buses, motorcycles, and bicycles are welcome aboard The CAT—and walk-on passengers. Dogs and cats are welcome and can be transported in the onboard kennel area. Guests traveling with pets should book as far in advance as possible to ensure kennel availability. Appropriate veterinarian-issued certificates may be required. Since this is an international ferry service, proper international travel documents are required. Only cats and dogs can travel on The CAT. Pets can travel in their owner’s vehicle, or in an onboard kennel. Owners are not allowed to visit their pet during passage, therefore you must leave them with adequate food and water supplies.
