Shipping Cats Across Country

Shipping a Cat Across the Country: What to Know Before You Book

Moving a cat cross-country by air is straightforward for most cats, but a few decisions early in the process determine whether it goes smoothly. Here is what you need to think through before you book transport.

Cabin or Cargo: Which Applies to Your Cat?

Most domestic carriers allow small cats in the cabin as carry-on, provided the cat plus carrier fits under the seat and stays within the airline's combined weight limit. Carriers such as Alaska, American, Delta, and United each allow cabin pets on most domestic routes, but eligibility varies by route, aircraft type, and the number of pets already booked on that flight. Confirm directly with the airline before purchasing your ticket, and do not assume availability.

If your cat is too large for cabin travel, or if you are shipping without traveling alongside your cat, cargo is the alternative. For most healthy cats, cargo is safe when handled by an airline with proper live animal procedures. Brachycephalic cats (Persians, Himalayans, Exotic Shorthairs) face more restrictions due to their respiratory anatomy, and some carriers will not accept them in cargo at all. Confirm your cat's breed eligibility before booking.

Health Certificate Requirements

Most airlines require a health certificate from a licensed veterinarian issued within 10 days of travel. This is a standard document confirming your cat is healthy and fit to fly. Your vet will examine your cat and complete the certificate at the appointment.

Even if your airline does not require one, it is worth getting. If your cat is flagged for any reason at check-in or cargo drop-off, a clean health certificate removes one potential obstacle immediately.

Do Not Sedate Your Cat for Travel

Do not sedate your cat before a flight. Sedation affects balance and thermoregulation, and both become more unpredictable at altitude. Most airlines will refuse to accept a sedated cat, and if something goes wrong mid flight, sedation complicates the situation. If your cat is highly anxious, talk to your vet about non sedating options such as pheromone sprays or a calming supplement, and get clearance before using anything on travel day.

Crate Preparation

Your cat's crate needs to meet IATA Live Animal Regulations standards whether they travel in cabin or cargo. For cabin travel, the carrier needs to fit under the seat in front of you. For cargo, the crate must be hard-sided, ventilated on at least three sides, and large enough for your cat to stand, turn, and lie down without touching the walls.

The most important thing you can do before travel day is get your cat comfortable with the crate well in advance. A cat that treats the crate as a familiar space handles the noise, movement, and confinement of a flight significantly better than one encountering it for the first time at the airport.

Ground Transport: A Real Alternative for the Right Cat

Air travel is not the only option. For moves where timing is flexible, or for cats that are poor candidates for flying due to anxiety, health conditions, or breed restrictions, ground transport is worth considering. There are no altitude variables, no cargo hold, and no airline eligibility rules to navigate. The tradeoff is time: a cross-country ground move takes several days rather than a few hours.

PetRelocation offers ground transport for domestic moves. If you want to explore whether it makes sense for your cat's specific situation, talk to our team and we can walk through the options.

State Specific Rules to Check

Most domestic destinations have no special entry requirements for cats. Hawaii is the main exception. It has strict pet import rules, including a quarantine program, that apply even to moves from the continental US. Treat a Hawaii move as you would an international relocation in terms of lead time and paperwork.

A few other states have specific requirements around health certificates or interstate transport. Check your destination state's department of agriculture website for current requirements before travel.
