If you have two cats, getting both to the vet or on a road trip can mean juggling two carriers. Double carriers solve that with two compartments in one bag, usually separated by a removable divider. The best cat carriers for two cats keep each cat secure and separated, give both enough room, are well ventilated and are comfortable for you to carry. Below we compare four options on Amazon, and explain when two separate carriers are still the better choice.
A quick note: many vets and cat behaviorists recommend one carrier per cat, because stressed cats can redirect fear onto each other, even if they are bonded at home. Double carriers with a solid divider are a good compromise for car travel with calm, bonded cats.
Cat Carriers for Two Cats Compared
| Carrier | Type | Divider | Best For |
|---|---|---|---|
| Expandable Double Carrier with Litter Boxes (LitaiL) | Soft-sided, expandable | Removable | Best overall, road trips |
| Expandable Double Carrier for 2 Large Cats | Soft-sided, 3-in-1 expandable | Removable | Larger cats and long drives |
| Double-Compartment Rolling Backpack | Backpack with wheels | Fixed compartments | Carrying two small cats on foot |
| Petmate Two Door Deluxe Kennel | Hard-sided, single compartment | None (one per cat recommended) | Vet visits and safety |
1. Expandable Double Cat Carrier with 2 Litter Boxes — Best Overall
This double carrier has two compartments separated by a removable divider, mesh on four sides and the top for airflow and visibility, and expandable sections that give each cat more room when you stop. It comes with two portable litter boxes for long car trips, and the listing says it holds up to about 30 pounds total. It is a practical setup for road trips and moves with two cats.
- Removable divider keeps cats apart
- Expandable for extra room
- Two portable litter boxes included
- Mesh on multiple sides
Worth knowing: It is bulky once expanded, so it is best for car travel rather than carrying long distances.
2. Expandable Double Carrier for 2 Large Cats — Best for Large Cats
Another soft, expandable double carrier, this one is aimed at larger cats, with extra-roomy compartments, ventilation panels and two portable litter boxes. The 3-in-1 design lets you use it as two separate spaces or open it up into one big den for bonded cats during rest stops. It collapses for storage when you are not traveling.
- Roomy compartments for bigger cats
- Converts between divided and open
- Portable litter boxes included
- Collapses for storage
Worth knowing: Measure your car’s back seat or cargo area; expanded double carriers take a lot of space.
3. Double-Compartment Rolling Cat Carrier Backpack — Best for Carrying
Carrying two cats is heavy. This backpack-style carrier has two compartments and built-in wheels, so you can wear it on your back or roll it like luggage through parking lots and waiting rooms. The listing rates it for up to about 12 pounds per cat, so it suits small to average-size cats.
- Wear as a backpack or roll on wheels
- Two separate compartments
- Good for vet visits on foot
- Ventilated panels
Worth knowing: Not suited to large cats; check each cat’s weight against the limit.
4. Petmate Two Door Deluxe Kennel (Intermediate) — Best Separate-Carrier Option
If your cats do not get along in tight spaces, or you mostly travel to the vet, two sturdy hard carriers are the safest option. Petmate’s two-door kennel has a top door that makes it much easier to lower a reluctant cat in, and a front door for walking out. The hard shell protects better than fabric in a car and is easy to clean after an accident. Buy one for each cat.
- Top and front doors
- Hard shell protects in the car
- Easy to clean
- Keeps each cat fully separate
Worth knowing: The intermediate size is roomy for one cat; we do not recommend putting two cats in one hard kennel.
How We Chose These Carriers
We compared double carriers on divider design, ventilation, size, weight limits and ease of carrying, and included a hard-sided kennel for owners who prefer separate carriers. Several double carriers on Amazon come from smaller brands, so we focused on designs with clear specifications and plenty of owner feedback. Prices change often, so we do not list them; check current prices and reviews with the buttons. For single carriers, see our best cat carriers guide.
Double Carrier vs Two Separate Carriers
| Double Carrier | Two Separate Carriers | |
|---|---|---|
| Convenience | One bag to manage | Two to carry |
| Safety if cats squabble | Divider helps, but cats can still see and hear each other | Best, fully separate |
| Car travel | Good for long road trips | Good, buckle in both |
| Vet visits | Fine for calm, bonded cats | Often recommended by vets |
| Weight to carry | Heavy; look for wheels or car use | Split between two hands |
Tips for Traveling With Two Cats
- Carrier-train both cats. Leave carriers out at home with bedding and treats so they become familiar resting spots.
- Keep them separated in transit. Use the divider, even for bonded cats, to prevent stress-related squabbles.
- Secure the carrier. Buckle it with a seatbelt or wedge it on the floor behind a front seat so it cannot slide.
- Cover part of the carrier with a light towel to help anxious cats feel hidden, while leaving ventilation open.
- Bring familiar scents such as a worn blanket from home.
- Ask your vet about long trips or very anxious cats.
Care and Cleaning
Line compartments with absorbent pads for longer trips. After each use, remove and wash the bedding and wipe the interior with a pet-safe cleaner. Check zippers, mesh and the divider for damage before every trip; a determined cat can find a weak spot. Hard kennels can be washed with warm soapy water and dried fully before storage.
Our Verdict
For road trips with two calm cats, the Expandable Double Carrier with Litter Boxes is the best overall choice. Pick the Expandable Double Carrier for Large Cats for bigger cats and the rolling backpack if you carry two small cats on foot. For vet visits, or cats that squabble, two Petmate Two Door kennels are the safest option.

Frequently Asked Questions
Can two cats share one carrier?
It is generally safer to keep them separated. A double carrier with a divider or two separate carriers prevents stressed cats from fighting in a small space.
Are double cat carriers safe for car travel?
Yes, when the carrier is secured with a seatbelt or placed on the floor so it cannot slide, and the divider is in place.
What size carrier do two cats need?
Each cat should have enough room to stand, turn around and lie down. Check weight limits per compartment, not just the total.
Do vets prefer separate carriers?
Many do, because it is easier to handle each cat and reduces stress-related fights. Ask your vet what they prefer.
How do I get two cats into one double carrier?
Carrier-train each cat separately first, then load one cat at a time into its own compartment with treats. Top-opening designs make it easier.
