Our top recommendation: rocket & rex Pet Carrier Replacement Pads
rocket & rex combines four absorbent layers, waterproof backing, machine washing, and low-heat drying in a two-pad rotation. The exact 17.5-by-11-inch size is the advantage and the constraint: measure the carrier floor rather than trusting a medium label.
- Best for
- Standard medium soft-sided carriers that fit a 17.5-by-11-inch washable pad
- Buying note
- $15.95 for two at research time; official site showed the carrier-specific pack sold out, so confirm restock.

Decision first
Quick picks
The short answer
Choose rocket & rex for a thin reusable two-pad rotation when 17.5 by 11 inches fits. Choose Sherpa for a softer washable liner with waterproof backing. Choose DryFur for a disposable insert that stays flatter and offers four documented size ranges.
The best liner is the one that fits the carrier floor exactly and can be replaced without opening the carrier in an unsafe location.
Compare reusable and disposable formats
| Pick | Format | Moisture barrier | Main constraint |
|---|---|---|---|
| rocket & rex | Washable four-layer pair | Waterproof backing | One carrier-specific size, stock |
| Sherpa | Washable faux lambskin pair | Waterproof bottom | Added thickness |
| DryFur | Disposable rigid-core pair | Absorbent disposable structure | Recurring waste and cost |
How we chose
We required explicit absorbency or leak-barrier documentation, current sizing, and a product intended for pet carriers. We compared washability, backing, fit range, bunch resistance, thickness, spare rotation, price, and current stock.
This is not a laboratory absorbency test. We did not compare liquid volume, drying speed, odor retention, or performance after repeated washes.
Fit the floor before choosing softness
A liner that curls at the door can interfere with a latch. A pad that is too small leaves the base exposed. Measure the usable interior and check the carrier with the pad installed, including the cat’s standing and turning room.
Our cat carrier selection guide covers ventilation, structure, entry, and vehicle use. A liner improves cleanup but cannot correct a poorly fitted carrier.
Build a two-liner change routine
Pack at least one clean spare in a sealed dry bag and a separate sealable bag for the used liner. Plan changes only in a secure enclosed space where the cat cannot escape. Never open a carrier at a roadside shoulder or open rest area.
A pet travel organizer for cat road trips can keep the spare at the top rather than beneath food and luggage.
Washable and disposable solve different trips
Washable pairs make sense for routine vet travel and repeated drives when laundry access is predictable. Disposable rigid pads simplify flights or moves where a wet reusable liner cannot be washed immediately. Some owners use a washable liner for normal comfort and carry a disposable backup.
Follow each care label. Bleach, softener, high heat, or incomplete drying can damage absorbency or waterproof layers.
Bottom line
rocket & rex offers the clearest low-profile reusable system, Sherpa adds softness, and DryFur offers the simplest disposable change. Measure first, carry a spare, and preserve the carrier’s usable space.
Research shortlist
The picks in detail
rocket & rex Pet Carrier Replacement Pads
Best for: Standard medium soft-sided carriers that fit a 17.5-by-11-inch washable pad
rocket & rex combines four absorbent layers, waterproof backing, machine washing, and low-heat drying in a two-pad rotation. The exact 17.5-by-11-inch size is the advantage and the constraint: measure the carrier floor rather than trusting a medium label.
Why it stands out
- Washable four-layer construction
- Waterproof backing
- Two pads support clean-spare rotation
Watch-outs
- Sold out on the official site at research time
- One published carrier size
- Fabric softener and bleach can reduce performance
Sherpa Replacement Liners
Best for: Owners who want a soft absorbent surface, waterproof backing, and several carrier-matched size listings
Sherpa's machine-washable faux-lambskin liner adds absorbency and a waterproof bottom in packs of two. It is a comfortable reusable choice, but thick pile must not reduce the cat's usable height or interfere with the carrier floor and closure.
Why it stands out
- Soft absorbent faux-lambskin surface
- Waterproof backing
- Machine washable two-pack
Watch-outs
- Pile adds more thickness than a flat pad
- Size names still require measurement
- White surface shows travel soil quickly
DryFur Super Absorbent Travel Pads
Best for: Air or road trips where immediate disposal and a pad that stays flat matter more than reuse
DryFur uses a cushioned rigid core and flexible wings to stay flat while absorbing liquid, with four published carrier-floor ranges. It is the easiest mid-trip disposal option but creates recurring cost and waste compared with washable pairs.
Why it stands out
- Four documented size ranges
- Rigid core resists bunching
- Disposable after a travel accident
Watch-outs
- Not reusable
- Ongoing cost and waste
- Flexible wings need correct size selection

Frequently asked questions
How do I measure a cat carrier for a liner?+
Measure the usable interior floor at its narrowest length and width, not the carrier's exterior. The pad should lie flat without folding over vents, latches, drain channels, or door hardware.
Is waterproof backing enough for a long trip?+
It reduces leak-through but does not make cleanup automatic. Carry a spare liner, sealed bag, gloves, cloths, and manufacturer-appropriate cleaner. Replace a wet pad promptly in a secure enclosed location.
Can a thick liner make a carrier too small?+
Yes. A plush pad reduces usable interior height and can affect the cat's ability to stand, turn, or lie naturally. Recheck fit with the liner installed and make sure doors and base panels close normally.
