Updated for 2026 with current airline policies for multiple cats and the latest carrier recommendations.

Traveling With Two Cats: Double the Challenge

Dogs may be the stars of the pet travel world, but a significant number of us travel with cats — and traveling with two cats simultaneously is an experience that defies simple advice. I know this because my partner and I have traveled with our two cats, Miso and Tempeh, on three cross-country road trips, seven flights, and more hotel stays than I want to count. Two cats in a car is not just double the work of one cat. It is double the meowing, double the litter logistics, double the carrier space, and approximately quadruple the anxiety.

But it is also possible, and it can even be pleasant once you have your system dialed in. This guide covers every aspect of traveling with two cats — from carrier selection and car setup to airline logistics and hotel management. If you are reading this because you have an upcoming trip with two cats and no idea how to handle it, take a deep breath. You are going to be fine.

Carrier Selection for Two Cats

The first decision is whether your cats will travel in one carrier or two separate carriers. The answer depends on the type of travel and your cats’ relationship.

One Carrier vs. Two Carriers

Factor	One Shared Carrier	Two Separate Carriers
Cat relationship	Only if cats actively seek each other’s company	Always safe; necessary if cats have any conflict
Air travel	NOT allowed — airlines require one carrier per cat	Required by all airlines
Car travel	Possible for bonded pairs	Recommended for all cats
Space required	One large carrier (takes up one seat)	Two carriers (takes up the entire back seat)
Weight management	Combined weight must not exceed carrier weight limit	Each carrier holds one cat
Escape risk	Lower — cats calm each other	Higher — two carriers to secure
Stress level	Lower for bonded pairs	Lower for cats that prefer personal space

My recommendation: Always use two separate carriers unless your cats are a genuinely bonded pair that sleeps together, grooms each other, and shows distress when separated. Even bonded cats can become aggressive in stressful travel situations when confined together, and a carrier fight is the last thing you need at 70 mph on the interstate.

Best Carriers for Two-Cat Travel

For air travel (cabin, one cat per carrier):

Carrier	Dimensions	Airline Fit	Weight Capacity	Price
Sherpa Original Deluxe (Medium)	17x11x10.5”	Most airlines	16 lbs	$55-$75
Sleepypod Air	21x10x9”	Most airlines	15 lbs	$180
SturdiBag Large	18x12x12”	Most airlines	18 lbs	$70
Roverlund Airline Compliant	18x11x11”	Most airlines	20 lbs	$145

When flying with two cats, you need two separate airline-approved carriers, and you need two separate under-seat spaces. This means you either need two passengers (each responsible for one carrier) or you need to purchase an extra seat. Most airlines limit one pet per passenger.

For car travel:

Carrier	Type	Best For	Price
Petmate Sky Kennel (Intermediate)	Hard-sided	Maximum safety	$60-$90
Sleepypod Mobile Pet Bed	Soft/hard hybrid	Comfort + car safety	$180
SportPet Foldable Travel Cat Carrier	Hard-sided, foldable	Storage when not traveling	$30-$50
Necoichi Portable Ultra Light Cat Carrier	Ultra-lightweight	Short car trips	$30

For car travel with two cats, I recommend two hard-sided carriers secured on the back seat with seatbelts threaded through the handle openings. Hard-sided carriers are safer in a collision and easier to clean than soft-sided options.

Car Travel With Two Cats

Car Setup

Carrier placement: Place both carriers on the back seat, side by side if your seat is wide enough, or one on the seat and one on the floor (elevated slightly with a towel to reduce vibration). Never place carriers in the cargo area of an SUV or trunk of a sedan — temperature regulation is poor and crash safety is minimal.

Securing the carriers: Thread the seatbelt through the carrier handle or use bungee cords to prevent sliding. In a sudden stop, an unsecured carrier becomes a projectile — dangerous for the cat inside and for the car’s occupants.

Temperature control: Cats are sensitive to both heat and cold. Maintain the car interior between 65 and 78 degrees. Direct sunlight on a carrier can cause rapid overheating — use window shades on the sunny side.

Sound management: Cats are sensitive to engine noise, road vibration, and music. Keep the radio low or off. Classical music or specially composed cat-calming music (yes, this exists — David Teie’s “Music for Cats”) has been shown in studies to reduce feline stress during transport.

The Litter Situation

This is the logistic challenge that separates cat travel from dog travel. Dogs go outside. Cats need a litter box. With two cats, you need a litter solution that is accessible during stops and manageable in a car.

Option 1: Disposable litter trays. Pre-filled disposable litter trays (like the Nature’s Miracle Disposable Litter Box) are the most convenient car travel option. Buy one per cat per day of travel. At rest stops, open the tray on the car floor, let each cat use it individually, then seal and dispose.

Option 2: Portable litter box. A small, collapsible litter box (like the Necoichi Portable Litter Box) takes up minimal space and can be lined with a plastic bag for easy cleanup.

Option 3: Puppy pads in the carrier. For short trips (under 4 hours), line each carrier with a puppy pad. This is not ideal for longer trips because most cats will not eliminate while confined in a carrier, but it provides an emergency option.

Litter stop protocol:

1. Park in a quiet, flat area (not a busy rest stop)
2. Close all car doors and windows except the one you are working through
3. Set up the disposable litter tray on the car floor
4. Open one carrier at a time and let the cat access the litter tray
5. Most cats will use it immediately, especially after 2+ hours in a carrier
6. Return the cat to the carrier, clean the tray, and repeat with the second cat
7. Never open both carriers simultaneously — two loose cats in a car is a recipe for chaos

Feeding and Water

• Withhold food 4-6 hours before departure to reduce nausea
• Offer water at every stop (minimum every 2-3 hours)
• Attach a small water dish to the inside of each carrier for long drives
• Feed a light meal when you stop for the night, not during the drive
• Bring the exact food your cats eat at home — diet changes plus travel stress equals digestive disaster

Dealing With Meowing

Two meowing cats in a car can test the patience of a saint. Here is what works:

Calming pheromones. Spray Feliway Classic on the carrier bedding 30 minutes before loading the cats. Feliway mimics the feline facial pheromone that cats deposit when they rub their cheeks on objects, signaling safety and comfort. Clinical studies show a modest but real reduction in stress behaviors during transport. International Cat Care has additional resources on reducing feline travel stress.

Covering the carriers. Drape a light, breathable towel over each carrier. Cats feel more secure when they cannot see the moving world outside. This alone reduces meowing in most cats.

Gabapentin. This is the game-changer for cat travel. Gabapentin at 50-100 mg per cat, given 2-3 hours before travel, produces mild sedation and significant anxiety reduction. It is the most commonly prescribed travel medication for cats and is remarkably safe. Your vet can prescribe it after a brief consultation.

Ignoring the meowing. This is counterintuitive, but responding to meowing (talking to the cats, reaching back to the carriers) often increases the behavior because you are reinforcing it with attention. If the cats are safe, hydrated, and at a comfortable temperature, the meowing will eventually reduce as they settle.

What does NOT work: Playing loud music to drown out the meowing (increases stress), giving treats through the carrier door while driving (distracted driving), opening the carrier to comfort the cat while the car is moving (escape risk).

Air Travel With Two Cats

Airline Policies for Multiple Cats

Flying with two cats is logistically more complex than flying with one:

Airline	Cats Per Carrier	Carriers Per Passenger	Fee Per Carrier	Two Cats/One Passenger?
Delta	1	1	$150	No — need 2 passengers or extra seat
United	1 (2 kittens under 6 months may share)	1	$150	No (with kitten exception)
American	1	1	$150	No — need 2 passengers
Southwest	1	1	$125	No — need 2 passengers
JetBlue	1	1	$150	No — need 2 passengers

The bottom line: If you are flying alone with two cats, you generally need to purchase an extra seat for the second carrier. Some airlines allow this; others do not. Call the airline directly to ask about “extra seat for pet” options.

If you are flying with a partner: Each person books one cat as their in-cabin pet. This is the simplest solution and ensures each cat has its own carrier under its own passenger’s seat.

Airport Process With Two Cats

Check-in: Each cat is checked in separately. Have both health certificates, both carriers, and both pet reservation confirmations ready.

TSA screening: This is the most stressful part. You must remove each cat from its carrier and carry it through the metal detector while the empty carrier goes through the X-ray. With two cats, this means two trips through the detector or one person per cat.

Tips for TSA with two cats:

• Request a private screening room — this eliminates the risk of a cat escaping into the terminal
• Use harnesses with leashes as backup while cats are out of carriers
• Have treats ready to lure cats back into carriers after screening
• Stay calm — your anxiety transfers directly to your cats

Boarding: Board early when possible. Two carriers take time to arrange under two seats. On many aircraft, the under-seat dimensions are tight for one carrier — getting two situated requires patience.

During the flight:

• Each cat stays in its carrier under a separate seat for the entire flight
• Offer water via a small dish or wet food with high moisture content
• Place a finger through the mesh for reassurance — cats often calm down when they can feel your touch
• Expect meowing during takeoff and landing — pressure changes and engine noise increase stress

Hotel Stays With Two Cats

Room Setup

Hotel rooms with two cats require immediate catproofing:

1. Close the bathroom door. The toilet (drowning risk for cats) and any cleaning supplies under the sink need to be secured.
2. Check for escape routes. Cats fit through smaller spaces than you think. Check behind the desk, under the bed, and around window air conditioning units for gaps.
3. Set up the litter box immediately. Place a disposable litter tray in the bathroom (door closed with cats accessing through a propped-open gap, or in the main room in a corner).
4. Create separate spaces. If your cats need breaks from each other, designate the bathroom as one cat’s space and the main room as the other’s. Cats that travel together usually coexist fine but may need occasional separation in tight hotel rooms.
5. Block the area under the bed. Hotel bed frames often have gaps where cats can hide and refuse to come out. Stuff extra pillows or your luggage bag along the base to prevent hiding.

The Door Problem

The single biggest risk in hotel rooms is a cat escaping through an opened door. Housekeeping, room service, and your own entries and exits all present escape opportunities.

Prevention:

• Place a “Do Not Disturb” sign on the door permanently during your stay
• Put both cats in carriers before opening the door for any reason
• If you must leave cats loose in the room, create a barrier system: put cats in the bathroom, close the bathroom door, then open the main door
• Inform the front desk that you have cats and request that housekeeping not enter without your presence

Nighttime

Two cats in a hotel room at night can be surprisingly active. Cats are naturally crepuscular (most active at dawn and dusk) and may use the nighttime to explore, play, and knock things off surfaces.

• Remove all small objects from accessible surfaces before bed
• Provide enrichment (a crinkle toy, a puzzle feeder) to occupy them
• If the noise is unbearable, crate both cats for sleeping — this is not cruel if they are crate-trained and the crates are comfortable
• Use white noise to mask the sound of hotel hallway activity that might stimulate the cats

Reducing Travel Stress for Two Cats

Pre-Trip Preparation (Start 4 Weeks Before)

Week 1-2: Carrier acclimation.

• Place both carriers in your living area with doors open
• Feed treats inside the carriers
• Build to feeding meals inside the carriers
• Leave the carriers out permanently so they become furniture, not threat objects

Week 3: Short car rides.

• 5-minute drives to nowhere and back
• Carrier in the car, secured, with cats inside
• Treat on arrival home
• Build to 15-minute drives by end of week

Week 4: Dress rehearsal.

• Load both cats, both carriers, and all supplies into the car
• Drive for 30-60 minutes
• Practice a litter stop
• Return home and evaluate what worked and what needs adjustment

Calming Aid Comparison for Cats

Product	Type	Effectiveness	Cost	Best For
Gabapentin (Rx)	Oral medication	High	$5-$15 per dose	Moderate to severe anxiety
Feliway Classic Spray	Pheromone spray	Moderate	$15-$20 per bottle	Carrier and environment calming
Composure Pro (Vetriscience)	Supplement	Mild-Moderate	$25 per 30-count	Mild anxiety
Rescue Remedy Pet	Flower essence	Minimal (placebo-level)	$12-$15 per bottle	May help some cats
ThunderShirt for Cats	Pressure garment	Variable	$40	Some cats respond well

My ranking: Gabapentin is the most effective option by a significant margin. I give both Miso and Tempeh 100 mg gabapentin 2 hours before any travel over 30 minutes, and the difference is dramatic — from panicked meowing to drowsy contentment.

Signs of Excessive Stress

Monitor both cats throughout travel for signs that stress is becoming dangerous:

• Open-mouth breathing or panting (emergency — cats do not pant normally; this indicates severe stress or overheating)
• Urinating or defecating in the carrier (moderate stress)
• Complete silence and immobility (freeze response — a shutdown stress reaction)
• Aggressive behavior toward you when you open the carrier (redirected aggression from fear)
• Not eating or drinking for more than 12 hours after arriving at the destination

If you observe open-mouth breathing, pull over immediately, check the car temperature, and contact a veterinarian. Panting in cats can indicate respiratory distress, heatstroke, or cardiac issues.

Multi-Day Trip Planning With Two Cats

Route Planning

• Plan stops every 2-3 hours for litter box access and water
• Choose pet-friendly hotels along your route and confirm their cat policies (some “pet-friendly” hotels only allow dogs)
• Identify emergency veterinary clinics at each overnight stop
• Choose the most direct route — cats do not benefit from scenic detours
• Drive during the cooler parts of the day if traveling in summer

Packing List for Two Cats

• 2 carriers (appropriately sized)
• Carrier bedding (familiar-smelling blankets)
• Disposable litter trays (1 per cat per day, plus extras)
• Litter (small bag of their regular litter)
• Food (their regular brand, enough for the trip plus 3 days)
• Water from home (sudden water changes cause stomach upset)
• Collapsible water bowls (2)
• Food bowls (2)
• Gabapentin or other prescribed medication
• Feliway spray
• Paper towels and enzymatic cleaner
• Poop bags for disposing of used litter
• Favorite toys (1-2 per cat)
• Vaccination records and health certificates
• Harnesses and leashes (as backup during carrier transfers)
• Treats
• Small first aid kit

Final Thoughts

Traveling with two cats is twice the logistics but not twice the difficulty. The challenges are predictable and manageable: carrier space, litter management, meowing, and stress reduction. The solutions are proven: two separate carriers, gabapentin, Feliway, a systematic approach to rest stops, and patience with the inevitable chorus of complaints from the back seat.

Miso and Tempeh have now traveled with us for over four years. They are seasoned road trip cats who walk into their carriers voluntarily, settle within 20 minutes of driving, and explore hotel rooms with the confidence of cats who have done this before. That transformation took practice, preparation, and a lot of gabapentin prescriptions — but it happened, and it can happen for your cats too.
